Subject: CPU usage for 10Gbps UDP transfers
Date: Saturday, September 15, 2007 - 3:00 pm

Hello,

is it expected that application sending 8900bytes datagram through 10Gbps NIC
utilizes CPU to 100% and similarly the receiver also utilizes CPU to 100%.
Is it something wrong or this is quite OK?

(The box is dual single core Opteron 2.4GHz with Myricom 10GE NIC.)
