Subject: Why is LRO off by default on ixgbe?
Date: Wed, 23 Sep 2009 09:29:59 -0700	[thread overview]
Message-ID: <4ABA4D07.50107@candelatech.com> (raw)

I just noticed that enabling LRO on ixgbe lets me reach about 9Gbps receive on two
NICs concurrently in an NFS test, where I was only getting about 6Gbps w/out it (1500 MTU).

Why is LRO disabled by default?

Thanks,
Ben
