said by Steve:
Can TX and RX buffer sizes be tuned separately? I would think that for web-type service, maxing out the TX buffer and minimizing the RX buffer would make a big diff in scaling.
If they can't be, then this smells like a great optimization to add to the kernel.
tcp_rmem - 4096 87380 16777216
tcp_wmem - 4096 87380 16777216
tcp_mem - 98304 131072 196608
I think those are min/default/max
edit: I bet Apache opens sockets with its own settings.--
