As promised (well, I've posted link to the "article" on nginx mailing list, so it was about time..) I'm posting configuration files (.tar.bz2) and script (.sh.txt) that helped me with my benchmarks.
About configuration files: Most of them are basic, out-of-the-box (or debian package) configurations, trimmed down to minimum. I don't say they are fully optimized, and I will appreciate any constructive comment or change suggestion.
About the script: this is my first "bigger" (longer then 10 lines, with functions, conditions and loops, all in one) bash shell script, so be gentle ;>
Some interesting issues were raised on the mailing lists, as:
- serving such a small file I was mostly measuring connection and http protocol overhead -- point taken, I'll try to repeat tests with biger file.
- number of failed requests (if any) -- will add this.
- average time request and time for longest request -- will add this to.
And some additional details about the test:
- Tests were ran on same machine as web servers
- ApacheBenchmark was used
- Before each test all web-servers were shutdown and killed

- VPS software: VMWare Workstation 6.0.1 build-55017
I'll try to make another test by the end of this week.
