So am I misreading this or did both nginx and lighttpd beat litespead by pretty hefty margins in the single AB client test?

@scenesrv -- can you tell us what optimizations you made to apache and/or what third party modules you compiled it with? It would also be helpful if you could tell us a bit more about the optimizations made to the other webservers.

LiteSpeed setup is optimized for multiple CPU setup. I will post multiple ab test results for nginx and lighttpd.

In a similar one-CPU license setup, LiteSpeed only uses about 40% of one CPU, while lighttpd uses about 80% of one CPU during the test.

And lighttpd does really bad for keepalive tests, I will post some results.

[mistwang]

lighttpd with 4 ab clients results:

2341.23 + 1950.79 + 1834.44 + 1745.66 = 7872.12

Four ab clients

LiteSpeed : 3667.72 + 3647.92 + 3629.93 + 3621.99 = 14567.56 req/s
Nginx: 2459.93 + 1945.81 + 1935.54 + 1911.70 = 8252.98 req/s
lighttpd: 2341.23 + 1950.79 + 1834.44 + 1745.66 = 7872.12 req/s

With 8 ab clients, nginx and lighttpd still only able to deliver 7000-8000 req/s,
while LiteSpeed can deliver 24000 req/s

SceneSRV -- would you be willing to confirm this?

[SceneSRV]

Yes, that's true.

[mistwang]

After a little bit of tuning of LiteSpeed, a setup optimized for 1-CPU setup like lighttpd can deliver 7769.82 req/s with 30% CPU utilization
