I think it doesn't really matter how much squid sets its default buffer.
The linux kernel will upscale to the maximum set by the third option.
(and the TCP Window Size will follow that)
net.ipv4.tcp_wmem = 1024 32768 8388608
net.ipv4.tcp_rmem = 1024 32768 8388608

If thats not fast enough, you may also wish to patch in a larger value

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.
