mistwang and NiteWave just a question. In above tests, Litespeed 4.0.18 had smart keep alives enabled. Looking up the function it doesn't mention specifically how it treats php files ?

Smart Keep-Alive
Description: Specifies whether to turn on Smart Keep-Alive. This option is effective only if Max Keep-Alive Requests > 1. If enabled, you can also enable/disable it at virtual host level. Smart keep-alive will only establish keep-alive connections for requests of JavaScript, CSS Style Sheet and image files. For html pages, connection will not be kept alive. This will help serve more users more efficiently. Normally a web page contains multiple images and scripts that will be cached by the browsers after initial request. It is more efficient to send those non-html static files through a single keep-alive connection and have the text/html file send through another non-keep-alive connection. This method will reduce idle connections and in turn increase capacity to handle more concurrent requests and users.

Update: Looks like Litespeed with Smart Keep-Alive OFF (which is default) is better than with it On.









And the interesting results,

Apache + Varnish
vs
Litespeed Cache with Smart Keep Alives On vs Off
