This is following up a previous SysKonnect/NetGear/Intel GigE discussion on CPU utilization. I heard people talking that using Jumbo Frame on these GigE adapters will use less CPU time. Since I have not gotten a chance to paly the Jumbo Frame on these NICs, and it seems all these cards have the similar CPU utilization issue, I would like to know which part of the drive process that chews more CPU when using the smaller MTU than using the larger MTU (assume without zero memory copy)? -Jin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
