, but they came out essentially in a dead heat when testing for raw throughput. *[image: userimage]Scott Larson[image: los angeles] <https://www.google.com/maps/place/4216+Glencoe+Ave,+Marina+Del+Rey,+CA+90292/@33.9892151,-118.4421334,17z/data=!3m1!4b1!4m2!3m1!1s0x80c2ba88ffae914d:0x14e1d00084d4d

ts and NIC counters show any drops or errors? On the FBSD servers you could also run 'netstat -i -w 1' under load to see if drops are occurring locally, or 'systat -vmstat' for resource contention problems. But again, a similar setup here and no such issues have appeared. *

Re: net.inet.ip.forwarding impact on throughput

Thanks Navdeep, I figured there had to be more going on than just allowing packets across interfaces. With forwarding automatically disabling TSO/LRO that would entirely explain why my bandwidth throughput tests drop off significantly. *[image: userimage]Scott Larson[image: los angeles

net.inet.ip.forwarding impact on throughput

2015-04-21 Thread Scott Larson
rwarding does to the network stack. Does it ultimately put a lower priority on traffic where the server functioning as the packet router is the final endpoint in exchange for having more resources available to route traffic across interfaces as would generally be the case? *[image: userimage]Scott Larso
