Hello,
The one setting that I do suggest you keep is:
kern.ipc.somaxconn=512 (128 may be too low for http testing)
In our experience with Apache and clients that do not use
Keep Alive (are short lived), 512 is also very low. It
causes listen queue overflows and leads to a very low
throughput.

CPU_FASTER_5X86_FPU is not likely
For your consideration, bearing in mind I haven't read all details of the
challenge or the systems and therefore may suggest inappropriate, wrong or
dangerous things:

I recall a thread somewhere recently about pentiumpro being decidedly
