Re: packet drop with intel gigabit / marwell gigabit

I use netperf which is a pure network traffic tester I also just use basic 'ab/apache' tests which would also test HD/IO if getting large files.
For the 'em' driver I have seen some posts/cvs commit updates to the driver saying it now works better without polling then with polling. I think this is in -stable but it might just be in current. I haven't done any testing for a while.

Hi,

Just on a hunch, can you try putting the card in a different PCI slot? There may be interrupt routing issues.

okay, i will try it in a couple days


the card also has a sysctl for intr moderation. See man 4 sk. The
default changed with Pyun's updated driver, I think, but you could
play with that too.

Further I still have the feeling that your measurings are not
comparable.
