    Below is the analysis and the actual output of running the throughput test in https://github.com/gonzalop/mq, using examples/throughput/multiple_different_args.sh against a local VerneMQ MQTT server running in a podman conrtainer like:
podman run --replace -p 1883:1883 -e "DOCKER_VERNEMQ_ACCEPT_EULA=yes" -e "DOCKER_VERNEMQ_ALLOW_ANONYMOUS=on" --name vernemq1 -d vernemq/vernemq
and then another run using --network host.
Note that Paho v3 lacks features and checks present in v5 clients, so it's not really comparing apples to apples, but it's a good reference.
The analysis is what Gemini thought of the output from the client perspective.

    What follows is the analysis that Gemini did comparing the server performance for the mq based client with VerneMQ running in a local container with port mapping.
Server Performance Analysis: VerneMQ (Container) vs. Mochi (Bare Metal)

Date: January 16, 2026
Client Used for Comparison: mq (Go)
Context:

VerneMQ: Running in a Podman container (likely subject to bridge networking overhead).
Mochi: Running bare metal on the host (direct TCP loopback).

Executive Summary

Mochi (Bare Metal) demonstrates significantly lower latency and higher transaction rates for QoS 1 and QoS 2, maintaining a 1:1 publish-to-delivery ratio even under high concurrency.
VerneMQ (Container) excels in raw bandwidth (MB/sec) for large payloads, achieving nearly double the throughput of Mochi for 10KB messages, likely due to Erlang's efficient binary handling. However, it exhibits significant "backpressure" or processing lag under high concurrency for QoS > 0, where the End-to-End rate drops well below the Publish rate.

1. Small Packet Performance (20 Bytes)

This test measures the server's ability to handle a high volume of individual packets/requests per second.
QoS 0 (Fire & Forget)

Winner: Mochi
Mochi is nearly 2x faster in processing small messages end-to-end.

Mochi: ~379,000 msgs/sec (E2E)
VerneMQ: ~198,000 msgs/sec (E2E)

Note: VerneMQ saturated at ~200k, while the mq client was trying to push >1.6M. This clearly identifies the bottleneck at the server/container boundary.


QoS 1 (At Least Once) - 50 Workers

Winner: Mochi
Mochi maintained perfect synchronization, while VerneMQ struggled to keep up with acknowledgments.

Mochi: ~73,000 msgs/sec (Publish) -> ~73,000 msgs/sec (E2E)

Efficiency: 100% (Real-time processing)


VerneMQ: ~91,000 msgs/sec (Publish) -> ~14,000 msgs/sec (E2E)

Efficiency: ~15% (Severe processing lag or buffering)


QoS 2 (Exactly Once) - 50 Workers

Winner: Mochi

Mochi: ~43,500 msgs/sec (E2E)
VerneMQ: ~14,800 msgs/sec (E2E)


2. Large Payload Performance (10KB)

This test measures the server's data throughput capacity.
QoS 0 (Fire & Forget)

Winner: VerneMQ
VerneMQ demonstrates superior raw I/O performance for large data chunks.

VerneMQ: 987 MB/sec
Mochi: 569 MB/sec

This huge difference suggests VerneMQ (and likely the Erlang VM) is highly optimized for moving large binaries, whereas Mochi (Go) might be hitting limits related to memory copying, garbage collection on the server side, or simply that the container networking stack is surprisingly efficient for jumbo frames.

3. Stability & Reliability

Both servers were generally stable with the mq client. However, looking at the broader test data (including Paho clients):

Mochi: Experienced "Subscriber idle" timeouts with paho_v5 on large payloads, similar to VerneMQ.
VerneMQ: Dropped significant messages with paho_v5 on 10KB payloads (57% loss), whereas Mochi also saw drops but maintained slightly better consistency in some runs.

Conclusion


Metric
Recommendation


High TPS (Small Messages)
Mochi. It handles high request rates with minimal latency.


Transactional (QoS 1/2)
Mochi. It maintains real-time processing without the massive lag seen in VerneMQ.


High Bandwidth (Large Files)
VerneMQ. It is nearly 2x more efficient at moving raw bytes.


Deployment
Note: Comparing Bare Metal to Container is not strictly "apples to apples". Mochi benefits from zero docker-proxy overhead. However, the magnitude of the difference in QoS 1/2 suggests architectural differences in how acknowledgments are handled under load.

    Server Performance Analysis: VerneMQ (Host Net) vs. Mochi (Bare Metal)

Date: January 16, 2026
Configuration:

VerneMQ: Podman Container (--network host)
Mochi: Bare Metal (Host OS)
Client: mq (Go) - chosen for its high efficiency to stress-test the servers.

Executive Summary

Enabling host networking significantly improved VerneMQ's performance for small messages, closing the gap with Mochi.

VerneMQ is the winner for Raw Throughput (Large Payloads), pushing nearly 1 GB/sec.
Mochi remains the winner for Transaction Latency (QoS 1/2), handling acknowledgments significantly faster under load.


1. Throughput (Small Messages - 20 Bytes)

Network stack overhead is the primary bottleneck here.
QoS 0 (Fire & Forget)

Winner: Mochi (Narrowly)
VerneMQ saw a massive improvement from the previous container-net test (~200k -> ~328k msgs/sec E2E).

Mochi: ~379,000 msgs/sec (E2E)
VerneMQ: ~328,000 msgs/sec (E2E)

Note: VerneMQ accepted publishes at ~574k/sec but could only deliver ~184k-328k/sec end-to-end to the subscriber. Mochi was more balanced.


QoS 1 (At Least Once)

Winner: Mochi
Mochi is much more responsive with ACKs.

Mochi: ~73,000 msgs/sec (E2E) - Stable (1:1 Publish/Deliver)
VerneMQ: ~16,500 msgs/sec (E2E) - Severe Lag

Observation: VerneMQ accepted messages at ~99k/sec (Publish Rate) but the subscriber only received ~16k/sec. The broker buffered heavily or struggled to persist/forward fast enough.


2. Bandwidth (Large Payloads - 10KB)

Memory management and binary handling are the primary bottlenecks here.
QoS 0

Winner: VerneMQ
VerneMQ dominates in moving data.

VerneMQ: ~847 MB/sec (Throughput)

Reliability: 100% Delivery (200k/200k)


Mochi: ~569 MB/sec (Throughput)

Reliability: 100% Delivery (200k/200k)


VerneMQ's Erlang-based engine handles large binary payloads roughly 1.5x faster than Mochi's Go implementation in this test.
QoS 2

Winner: Mochi
When transactional guarantees are enforced, Mochi's lower latency logic prevails over raw bandwidth.

Mochi: ~232 MB/sec
VerneMQ: ~108 MB/sec


3. Stability Under Load


VerneMQ (Host Net): Much more stable than the NAT-ed version. It successfully handled the massive 10KB flood without dropping packets for the mq client (unlike paho_v5 which still failed).
Mochi: Consistent and predictable. It rarely buffers excessively, preferring to process messages synchronously-ish, which leads to lower peak "Publish Rates" but perfectly matched "End-to-End Rates".

Conclusion


Use Case
Recommended Server
Reason


Streaming Large Files/Video
VerneMQ
Superior raw throughput (850+ MB/s).


High-Speed RPC / Control Plane
Mochi
Much lower latency for QoS 1/2; tighter loop between publish and receive.


Massive Telemetry Ingestion (IoT)
VerneMQ
Can ingest at extremely high rates (high Publish Rate), even if subscriber delivery lags behind (Buffering).

    MQTT Client Performance Report: Host Networking Comparison

Date: January 16, 2026
Context: All tests run against VerneMQ using host networking (--network host) to eliminate Docker proxy overhead.
Executive Summary

The mq client retains its title as the most efficient and performant library, though paho_v3 remains a strong competitor in specific low-concurrency scenarios. paho_v5 continues to struggle with heavy memory usage and stability under load.


Feature
mq
paho_v3
paho_v5


Max Publish Rate (QoS 0)
~574k msgs/sec
~379k msgs/sec
~220k msgs/sec


Memory Efficiency
Excellent
Good
Poor (High Alloc)


Large Payload Stability
100% Delivery
98% Delivery
~40% Message Loss


QoS 1/2 Latency
Lowest
Competitive
High


Detailed Analysis

1. Throughput & Latency (QoS 0)

Switching to host networking unleashed higher throughput for all clients, but mq scaled best.

Small Packets (20B, 20 Workers):

mq: 574,344 msgs/sec (Publish Rate)
paho_v3: 379,463 msgs/sec
paho_v5: 200,781 msgs/sec
Result: mq is ~1.5x faster than v3 and ~2.8x faster than v5.


2. Reliability under Load (10KB Payloads)

This test stress-tests the client's internal buffering and the server's ability to ingest data.

QoS 0 (10KB, 1 Worker):

mq: 100% delivery (200k/200k) at 847 MB/sec.
paho_v3: 81% delivery (162k/200k) at 693 MB/sec.
paho_v5: 37% delivery (74k/200k) at 312 MB/sec.
Analysis: mq was the only client to successfully deliver the full workload without dropping messages or timing out.


3. Transactional Performance (QoS 1 & 2)

In the most demanding tests (50 workers, QoS 2), the broker became the bottleneck (dropping messages), but mq showed the lowest overhead.

QoS 2 (Small Packet, 50 Workers):

mq: 68,720 msgs/sec (Publish Rate)
paho_v3: 51,637 msgs/sec
paho_v5: 43,074 msgs/sec


4. Resource Efficiency (Memory & GC)

mq consistently demonstrates a superior memory profile, critical for long-running services.


Sample Run (QoS 0, 20 Workers):

mq: 111 MiB TotalAlloc, 47 GC cycles
paho_v3: 281 MiB TotalAlloc, 92 GC cycles
paho_v5: 1,137 MiB TotalAlloc, 681 GC cycles

Impact: paho_v5 spent significantly more CPU time on garbage collection, contributing to its lower throughput.


Conclusion

For high-performance Go applications:

mq is the recommended choice for high-throughput, low-latency, and memory-constrained environments.
paho_v3 is a viable alternative if protocol strictness or legacy compatibility is prioritized over raw speed.
paho_v5 shows significant performance regressions and should be avoided for high-load systems.

    MQTT Client Performance Report: VerneMQ (local container) Comparison

This report compares the performance of three Go MQTT clients—mq (this library), paho_v3, and paho_v5—based on throughput tests conducted against a VerneMQ broker.
Executive Summary

The mq client significantly outperforms both Paho implementations across all Quality of Service (QoS) levels. It is characterized by massive publish rates, superior memory efficiency, and higher stability under heavy load.


Feature
mq
paho_v3
paho_v5


Max Publish Rate (QoS 0)
~1.6 - 2.0M msgs/sec
~220k msgs/sec
~260k msgs/sec


Memory Pressure
Very Low (110MB Alloc)
Moderate (280MB Alloc)
Very High (1.1GB Alloc)


GC Impact
Minimal (36 cycles)
Moderate (90 cycles)
Severe (600+ cycles)


Stability (10KB payloads)
Stable (100% delivery)
Mostly Stable
Poor (>50% message loss)


Key Performance Indicators

1. Publish Throughput (Messages/Second)

The mq client demonstrates a specialized optimization for high-frequency publishing. At QoS 0 with small packets, it is consistently 6x to 10x faster than the Paho alternatives.

QoS 0 (20B, 1 worker): mq hit 1,623,779 msgs/sec vs paho_v5 at 260,427 msgs/sec.
QoS 0 (20B, 4 workers): mq hit 2,000,373 msgs/sec, saturating the local stack.

2. Reliability and Message Delivery

Under heavy load and large payload sizes (10KB), the mq client maintained full message delivery where others struggled.

Payload Stress (10KB, QoS 0):

mq delivered 200,000/200,000 messages at 987 MB/sec.
paho_v5 delivered only 85,089/200,000 messages (~57% loss) at 353 MB/sec.
paho_v3 delivered 198,396/200,000 messages.


3. End-to-End Latency & Rate

While the "End-to-End Rate" is often limited by the broker's processing capacity, mq consistently matched or exceeded the maximum possible throughput of the VerneMQ instance (~198k msgs/sec E2E for small packets).
4. Memory Efficiency and GC Overhead

The memory profile of mq is significantly leaner. For a standard 200k message run:

mq: ~110 MiB TotalAlloc / 36 GC pauses.
paho_v5: ~1,137 MiB TotalAlloc / 613 GC pauses.

The high GC count in paho_v5 suggests a high number of allocations per message, which steals CPU cycles from the application logic.

Conclusion

For high-performance Go applications, the mq library provides:

Lower Latency: By reducing internal overhead and memory churn.
Higher Throughput: Efficiently saturating the network and broker.
Better Predictability: Massive reduction in GC pauses ensures smoother performance under sustained load.
Metric	Recommendation
High TPS (Small Messages)	Mochi. It handles high request rates with minimal latency.
Transactional (QoS 1/2)	Mochi. It maintains real-time processing without the massive lag seen in VerneMQ.
High Bandwidth (Large Files)	VerneMQ. It is nearly 2x more efficient at moving raw bytes.
Deployment	Note: Comparing Bare Metal to Container is not strictly "apples to apples". Mochi benefits from zero docker-proxy overhead. However, the magnitude of the difference in QoS 1/2 suggests architectural differences in how acknowledgments are handled under load.
Use Case	Recommended Server	Reason
Streaming Large Files/Video	VerneMQ	Superior raw throughput (850+ MB/s).
High-Speed RPC / Control Plane	Mochi	Much lower latency for QoS 1/2; tighter loop between publish and receive.
Massive Telemetry Ingestion (IoT)	VerneMQ	Can ingest at extremely high rates (high Publish Rate), even if subscriber delivery lags behind (Buffering).
