MQTT client throughput and reliability report (mq, paho v3 and v5) with Mosquitto server 2.1.0 as backend.
Raw
aa_intro_mosquitto_v2.1.0.md

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 mosquitto MQTT 2.1.0 server running on a container with host networking.

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. Also note that I increased the max inflight in the mosquitto server documentation to 1000 in order for paho v3 not to fail QoS 0 tests.

The analysis is what Gemini thought of the output from both the client side and the server side perspectives.

MQTT Client Performance Report: Mosquitto v2.1.0

This report highlights the performance capabilities of the mq library, benchmarking it against standard ecosystem clients (Eclipse Paho v3 and v5) using a Mosquitto v2.1.0 broker.

Executive Summary

  • Industry-Leading Throughput: mq consistently delivers the highest message rates and throughput across all test scenarios, often outperforming alternatives by 2x to 3x.
  • Rock-Solid Reliability: While other clients struggled with stalls and message drops under high concurrency, mq maintained a 100% success rate in every single test configuration.
  • Superior Efficiency: Built with Go optimization in mind, mq operates with significantly lower memory overhead and reduced garbage collection pressure, ensuring smooth performance even under extreme load.

1. QoS 0: High-Speed Streaming

Fire-and-forget performance where raw speed is critical.

Workers Payload Client Rate (msgs/sec) Throughput (MB/s) Reliability
1 20B mq 435,963 8.32 100%
paho_v5 237,786 4.54 91% ⚠️
paho_v3 204,503 3.90 100%
4 1024B mq 345,510 337.41 100%
paho_v3 132,033 128.94 100%
paho_v5 129,770 126.73 65% ⚠️
20 20B mq 710,948 13.56 100%
paho_v5 199,997 3.81 100%
paho_v3 168,934 3.22 100%
50 10240B mq 64,052 625.52 100%
paho_v3 54,464 531.88 100%
paho_v5 - - Stalled

Highlight: In high-concurrency scenarios (20 workers), mq achieves ~3.5x the message rate of its nearest competitor.

2. QoS 1: Guaranteed Delivery

Ensuring at-least-once delivery without compromising speed.

Workers Payload Client Rate (msgs/sec) Throughput (MB/s) Reliability
4 128B mq 108,671 13.27 100%
paho_v3 77,267 9.43 100%
paho_v5 61,676 7.53 100%
20 1024B mq 112,766 110.12 100%
paho_v3 67,491 65.91 100%
paho_v5 31,312 30.58 82% ⚠️
50 10240B mq 49,225 480.72 100%
paho_v3 48,527 473.90 99%
paho_v5 9,941 97.09 59% ⚠️

Highlight: mq dominates in throughput even with the overhead of acknowledgement packets, saturating the broker's capacity while others falter.

3. QoS 2: Exact Consistency

The most demanding delivery guarantee.

Workers Payload Client Rate (msgs/sec) Throughput (MB/s) Reliability
1 1024B mq 23,192 22.65 100%
paho_v3 20,786 20.30 100%
paho_v5 18,530 18.10 100%
20 10240B mq 31,699 309.56 100%
paho_v3 29,372 286.84 100%
paho_v5 4,908 47.94 78% ⚠️

mq: Performance & Reliability Analysis

Uncompromising Stability

The most critical takeaway from this benchmark is mq's resilience. In scenarios where alternative clients (specifically Paho v5) experienced severe degradation—dropping up to 40% of messages or stalling completely due to internal deadlocks—mq remained stable. It successfully delivered every single message across all QoS levels, payload sizes, and concurrency settings (1 to 50 workers).

Optimized for Efficiency

mq proves that high performance does not require high resource consumption.

  • Lower Memory Footprint: In stress tests (50 workers, 10KB payload), mq allocated ~35% less memory (4.1 GB vs 6.3 GB) than Paho v3.
  • Reduced GC Latency: By generating fewer allocations, mq triggers significantly fewer Garbage Collection cycles, preventing "stop-the-world" pauses that can jitter real-time data streams.

Conclusion

For developers building mission-critical Go applications on top of Mosquitto v2.x, mq is the definitive choice. It offers a rare combination of best-in-class throughput, absolute reliability under load, and runtime efficiency, making it superior to existing community standards for high-performance workloads.

Mosquitto v2.1.0 Broker Performance Analysis (Server Perspective)

This report analyzes the performance limits and characteristics of the Mosquitto v2.1.0 broker based on high-throughput stress testing. The data was generated using the mq client to saturate the broker across various payload sizes, concurrency levels, and QoS settings.

1. Broker Saturation Points

The following absolute limits were observed for the Mosquitto v2.1.0 broker running in a local container environment. These represent the maximum sustained performance before saturation or client-side backpressure occurred.

Metric Peak Value Context
Peak Ingress Rate ~1.36 Million msgs/sec QoS 0, 20B payload, 20 workers (Publisher only)
Peak E2E Delivery ~710,000 msgs/sec QoS 0, 20B payload, 20 workers (Full roundtrip)
Peak Bandwidth ~635 MB/sec QoS 0, 10KB payload, 4 workers
Packet Handling Limit ~710k PPS Observed saturation point for small packets

Observation: The broker is capable of ingesting over 1 million messages per second, but the end-to-end delivery path (Ingress -> Routing -> Egress) saturates around 710k messages/sec.

2. QoS Overhead Analysis

Higher QoS levels introduce significant overhead due to the required acknowledgement handshakes (PUBACK, PUBREC, PUBREL, PUBCOMP). The table below compares the maximum End-to-End (E2E) rate and relative efficiency compared to QoS 0.

QoS Level Max E2E Rate (msgs/sec) Throughput Drop Efficiency Factor
QoS 0 ~710,000 - 100%
QoS 1 ~184,000 -74% 26%
QoS 2 ~97,000 -86% 14%

Note: Data derived from 20-worker and 50-worker tests where saturation was achieved.

3. Concurrency & Scaling

The broker demonstrates positive scaling up to a specific concurrency threshold, after which contention (context switching, lock contention) yields diminishing returns.

  • Sweet Spot: 4 to 20 Workers. The broker consistently delivered peak throughput in this range.
  • Saturation: At 50 Workers, performance regression was observed across most metrics.
    • QoS 0 Rate: Dropped from 710k (20 workers) to 636k (50 workers).
    • QoS 1 Rate: Dropped from 184k (20 workers) to 150k (50 workers).

Scaling Recommendation: For optimal throughput on this hardware, utilizing a moderate number of high-throughput connections (10-20) is superior to massive concurrency (50+).

4. Broker Stress Responses

Under extreme load, the broker remains stable, but client implementations behave differently, revealing how the broker handles "uncooperative" or "slow" clients.

  • Robustness: The broker successfully handled sustained 100% CPU load without crashing or disconnecting the mq client, which maintained 100% delivery rates.
  • Slow Consumer Handling: In tests involving paho_v5, significant message drops and stalls occurred. This indicates the broker may trigger buffer limits or socket backpressure for clients that cannot keep up with the ingress rate (e.g., Paho v5 dropped ~40% of messages at QoS 1/50 workers).

5. Key Server Stressors (Ranked)

Based on the magnitude of performance degradation, the following factors impact the Mosquitto v2.1.0 broker the most:

  1. QoS Level (Handshaking): The transition from QoS 0 to QoS 1/2 is the single largest performance cost, reducing capacity by 74-86%.
  2. Packet Frequency (PPS): Small messages (20B) stress the CPU more than bandwidth limits. The broker is CPU-bound by packet processing logic (routing, matching) rather than network I/O.
  3. Client Concurrency: Exceeding ~20 active high-throughput publishers causes context-switching overhead that degrades total system throughput.
