[Xen-users] Best Practices for PV Disk IO?

[Christopher Chen <muffaleta@xxxxxxxxx>]

I was wondering if anyone's compiled a list of places to look to
reduce Disk IO Latency for Xen PV DomUs. I've gotten reasonably
acceptable performance from my setup (Dom0 as a iSCSI initiator,
providing phy volumes to DomUs), at about 45MB/sec writes, and
80MB/sec reads (this is to a IET target running in blockio mode).

As always, reducing latency for small disk operations would be nice,
but I'm not sweating it. I just wondering if anyone's experienced
similar behavior, and if they've found ways to improve performance.

Cheers
