Nginx vs Node.js (clustered) static file Siege Benchmarks


Nginx vs Node.js (clustered) static file Siege Benchmarks

Just a noob playing around with node.js to see what it can do as a static file server compared to Nginx 1.2.7 web server. Ran Siege benchmark tests on local computer via Virtualbox CentOS 6.3 63bit server instance.

Siege Benchmark Summary

Quite interesting to see how well node.js clustered static file server scaled almost 2x times better in terms of transactions per second compared to Nginx web server (4,250 trans/s vs 2,118 trans/s) - especially at the higher concurrency levels. Also check out average response times (0.14s vs 0.23s), longest transaction time (1.10s vs 13.95s) and transaction availability numbers all in node.js's favour.

Test Target VirtualBox Server Config:

  • Xeon W3550 @3380Mhz with 4 cpu threads
  • 1280MB DDR3-1536Mhz
  • 20GB storage on 1TB Western Digital Black Caviar SATA disk

Servers Tested:

  • Centmin Mod Nginx v1.2.7 server with 4 worker_processes (port 80)
  • Centmin Mod node.js Cluster server (4 processes) (port 8080)

Siege benchmark test parameters:

  • Benchmark mode -b used
  • 100 to 600 concurrent users @500 reps and 5s delay
  • Cache validation enabled
  • Using Siege benchmark I ran Siege load test against a static html file which consisted of 50x lipsum auto generated paragraphs from lipsum.com in a html file named lipsum.html.

The lipsum.html file

  ls -lah /usr/local/nginx/html/ | grep lipsum
