That's what I was thinking ... So I guess I should activate Object Cache one day to get better performances (anyway, I'm quite satisfied with current performances).
But that means annoyance for livre migration right ?
I must flush the cache manually before any live migration operation or is it automatic ?

If there is no object cache enabled, 'cache=xxx' in QEMU option has no effect
