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.
