Subject: pre-fetching skb for delayed send
Date: Fri, 06 Jul 2012 16:10:40 -0700 [thread overview]
Message-ID: <4FF77070.7040705@candelatech.com> (raw)
Suppose one has a bridge-like thing that may store up packets
for a bit (100+ms) before sending them....
We notice that performance is very good if we can run with (near) zero
delay, but at higher delay, performance goes down significantly when attempting 10G
speeds. I assume this is because we are sending skbs that are no longer in the cache...
So, is there an easy way to pre-fetch an skb and it's related pages?
Thanks,
Ben
