Subject: Slow guest network I/O when CPU is pegged - Looking for acknowledgement from developers
Date: Fri, 07 Apr 2006 14:25:12 -0400	[thread overview]
Message-ID: <4436AE88.1080200@tektonic.net> (raw)

Ok, so we all know that guest network I/O is slow when the system CPU's 
are being utilized extensively whether it be from dom0 or from other 
guests.  Lots of people have written about this and I can post concrete 
tests if required.

I'm just looking for one of the Xen developers to acknowledge that they 
have been able to replicate the problem and it is indeed being worked on 
or will be sometime in the near future.  No one has acknowledged any of 
the previous threads on either list so I want to make sure it is an 
outstanding issue that is not being overlooked.

Thank you,
Matt Ayres

(Just ask for my tests and I'll paste the output / file a bug, but I 
think it's been an established bug and didn't want to make this e-mail 
too verbose.)
