Linode: Should I migrate from Xen to KVM (Worse Stream Performance)





Answer: I don't know...
I got worse single thread performance after migration.

The linode team migrated my KVM node to another host, much better





Linode "KVM" New Node "Stream" Performance @ 2015/06/26, 2nd Migration




The linode team migrated my KVM node to another host, much better!
The ping-response time reduced 10ms as well! (why?)

Anyway, it looks to be equivalent to (or a little better compared to)
original Xen VM host. Thanks.
