Some suggestions: - 'pciconf -lc' too can be used to check pcie link width. Look for pcie capability in the output. - IIRC the kernel auto adjusts TCP window size and one does not need to set it manually. - Set greater MTU size than default 1500. It helps reduce CPU loading. - Do not use file as source or destination unless you are sure disks and I/O paths are fast enough. 10Gbe means 1000+MB/s. Only storage beasts can handle that. BTW, is FreeBSD able to cache and buffer them all in memory? - Finally, use 'top' to make sure nothing is eating up all CPU cycles.
