Small Static File Benchmark

Comparing web server response time to requests for small static files


This benchmark compares the speed at which different web servers deliver small static files using both non-keep-alive and keep-alive connections both on regular HTTP and HTTPS.

Summary

  • LSWS HTTP Performance Gain

    Concurrent Users Keep-Alive Apache
    10 No 4.4x
    Yes 8.5x
    100 No 4.0x
    Yes 6.0x
  • LSWS HTTPS Performance Gain

    Concurrent Users Keep-Alive Apache
    10 No 5.5x
    Yes 2.0x
    100 No 5.5x
    Yes 2.4x

Notes:

  • The static file was 4.0K in size. We used such a small file to avoid saturating the network connection.
  • The test was performed over a 10GBps network connection to make sure network bandwidth did not become a bottleneck.
  • The benchmark simulated serving 10000 requests to 10 and 100 users.
