Compiling vLLM main from source on DGX Spark

I do all this SSH'd into the DGX Spark from another machine, so everything is terminal commands.

Install python dev dependencies and uv

sudo apt install python3-dev
curl -LsSf https://astral.sh/uv/install.sh | sh

import time
import numpy as NP
from redis import StrictRedis as redis

# a 2D array to serialize
A = 10 * NP.random.randn(10000).reshape(1000, 10)

# flatten the 2D NumPy array and save it as a binary string
array_dtype = str(A.dtype)

Benchmarking Nginx with Go

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.

So, these are the different settings we are going to compare:

• Go HTTP standalone (as the control group)
• Nginx proxy to Go HTTP
• Nginx fastcgi to Go TCP FastCGI
• Nginx fastcgi to Go Unix Socket FastCGI
