[Bug 1100843] Re: Live Migration Causes Performance Issues

[C Cormier]

Could you confirm that your .1 tests were on a freshly booted Guest OS?
Our hardware likely different... but your latencies are close to my Post
Restore times.

I just reproded with 1GB RAM and Single CPU.

-Pre Save-
Simple syscall: 0.0519 microseconds
Simple read: 0.1356 microseconds
Simple write: 0.1086 microseconds
Simple open/close: 1.0265 microseconds
local at cc-precise120402-raw:~/lmbench-3.0-a9/bin/x86_64-linux-gnu$ 

-Post Restore-
Simple syscall: 0.0500 microseconds
Simple read: 0.2125 microseconds
Simple write: 0.1913 microseconds
Simple open/close: 1.4482 microseconds
