I reported this a while ago and suggested to have the number of pending

I created an ab replacement based on kevent, and at least with my machines,
which are comparable to each other, the load on client dropped from 100% to
2% or something. ab just doesn't give meaningful results (if the client is
not way more powerful). With that new client I get very similar results for
epoll and kevent, from 1000 through to 26000 concurrent requests, the results
have been posted on kevent-homepage in october, I just checked it with new
version, but there's no significant difference.
this is the benchmark with kevent-based client:

btw, each result is average over 1,000,000 requests
and just for comparison, this is on the same machines using ab:

is this client avaialble? and what patches need to be added to the kernel to use
it?
