Yes- that was on a good kernel, with the patch reversed.
On a bad kernel, with the patch applied (2.6.16-git16):
tcp_wmem: 4096 16384 4194304
tcp_rmem: 4096 87380 4194304
tcp_mem: 98304 131072 196608
They seem to be identical, which makes sense, since most websites work
just fine.
I am sending tcpdump's privately to you and Stephen. If anyone else
wants to see them, just ask.
Daniel
