Re: [Xen-users] Problems with GPLPV network latency

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

Ian,
I see some of the same behavior - pings from my Windows-based domUs with GPL PV 
drivers have seemingly random latency times from < 1 ms to more than 8000 ms.  
The funny thing is that I *know* this isn't the actual latency, since I would 
notice a ping taking 8 seconds to get back - it happens very, very rapidly.  
There must be something in the GPL PV network driver code that is supposed to 
(help) compute this that is malfunctioning.
