A few questions or hints ... - What is the CPU usage during your network test (user, sys, intr, idle)? - Do you see errors in "netstat -i"? - Do you use jumbo frames? - Is polling enabled? - Are there any network-related sysctls (/etc/sysctl.conf) or kernel settings? Have you enabled kernel debugging features (INVARIANTS, WITNESS etc.)? - Do you have any packet filter rules (PF, IPF, IPFW)? Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
