Being the programmer of hssTVS ....
Well, I didn't enable epoll for Litespeed because you definitely state in your benchmarks that poll would give better results ... At least I did disable anything else that could degrade performance, like logfiles or htaccess.
I'd be happy to change any config you desire for the next round of benchmarks I do. I'll be also very happy to assist in configuring my hssTVS for your next benchmarks.
What I really missed in your benchmarks was testing the conditional get and HEAD request speed as those methods are usually heavily used too in real life.
That being said, the TVS server supporting dynamic content will be started after hssTVS reaches beta (with my definition of beta being finished and waiting for any bugs to show up before declaring it final).
