Subject: Bad read performance
Date: Sat, 26 Feb 2005 01:00:23 -0600 [thread overview]
Message-ID: <f1ec958c0502252300610e92cc@mail.gmail.com> (raw)
Hi,
I notice that domain 0 gives bad performance with disk I/O. Domain 0
was given about 55MB RAM. With the same configuration, Linux on raw
hardware gives far better performance. While a raw Linux OS gives a
disk read throughput of around 20MB/sec (without any caching effects),
dom0 (using the Xen.2.0.4 kernel with linux kernel 2.6.10) gives only
about 2-3MB/sec throughput.
Any pointers to the reasons for this difference will be greatly helpful.
Thanks,
pradheep.
