[Xen-devel] RE: Issues about domU suspending/resuming

["Gustavo Pimentel" <gustavo.pimentel@xxxxxxxxxx>]

It's not really a bug, but a performance analysis.
I'm using remus for a HA system and after a system analysis using remus log, I 
notice that suspending a the guest can oscillate between 0.299ms to 812.909ms. 
And the resuming of the same guest oscillates between 0.387ms to 1745,579ms. 
The guest it's a virtual machine with 64MB of RAM, without CPU load.

It's very strange this large range of values of the suspend/resuming of a guest.
