If thats not fast enough, you may also wish to patch in a larger value
for HTTP_REQBUF_SZ in src/defines.h to 64KB with a matching incease to
read_ahead_gap in squid.conf. That has had some mixed results though,
faster traffic, but also some assertions being hit.

I remember the thread about increasing the request buffer to 64K and it
looked so promising.
Is there any evidence of setting HTTP_REQBUF_SZ to 16K is stable in 3.5.x?

You may find that memory becomes your bottleneck at higher speeds.
8-16GB sounds like a lot for most uses, but when you have enough
connections active to drive Gbps (with 4-6x 64KB I/O buffers) there are
is lot of parallel pressures on the RAM.
