Performance Tuning

Control your network route :
Check arp_filter settings with sysctl
sysctl -a | grep arp_filter
A setting of 0 says uses any path
If more than one path between machines, set arp_filter=1
Look for increasing interrupt counts in /proc/interrupt or
increasing counters via ifconfig or netstat
