Hello,
i read something about buffered IO in some hypervisors. So most
hypervisors bufferes all disk operations and after a while take the cpu to
execute all operations as one block. Is this the standard behavior of xen
hypervisor?
No
I didn''t found any information about that. Is there any
possiblity to de-/activate it?
I don''t think so.
If you use file:/ (which is not recommended), then you''d get buffered
I/O. For everything else (including phy:/ and tap:/), you should get
unbuffered I/O.
Thanks for your Reply, but I don''t understand what you mean with
file:/,
phy:/ and tap:/. Can you explain please or give me some internet links?
Thanks,
