I wasn't aware that it would corrupt data even if SACK was off. It is very
possible this could have contributed to the problem.
However, I played around a bit, and found that if I disable sendfile in apache,
it runs much better. It seems that with sendfile enabled, some httpd processes
would start hogging up CPU, which would reduce the other servers' performance.
