I increase the number of contiguous connection only by 5, from 305 to 310, and you get 3 times slower response for always the same thing and repeated all the time. Very consistent and from different clients as well. You can do any variation of 10 to 300 connections and you will always get the same results, or very close to it. See that at the end as well for proof. So, I know I am hitting a hard limit someplace, but can't find where.
You've assumed that Apache is the bottleneck, but perhaps your benchmark tool could be limited in some way. I suggest you try with apache benchmark or some other tool just to verify the results. Apache (especially in the prefork model) is known to have concurrency issues. I doubt that there are knobs you can twist OpenBSD-wise that will compensate for Apache and somehow magically make it scale.
