[Xen-users] how to debug slow HDD performance in Windows 2003 domU ?
Hi
I''ve recently setup CentOS 5.1 x64, with a Windows 2003 Web x64 domU
and
assigned 1 CPU & 1GB RAM to it.
Today, which installing something in Windows, I notice that it takes
ages to install a program. Running xm top, it doesn''t seem like
it''s
running out of RAM or CPU, and checking Windows Task Manager, I can see
it consumes only 2 - 6% CPU, and 127MB RAM in total. So, I believe it''s
probably an IO problem then?
xentop - 14:07:05 Xen 3.1.0-53.1.21.el5

The server is a Dell PowerEdge 860, with a Dual Core 2.4Ghz Xeon CPU,
8GB DDRII-667 RAM, and 750GB SATAII HDD.
Installing something in a CentOS domU was very quick, so I also presume
it''s something Windows specific, but this is my first Windows domU
attempt, so I don''t know what to look for.
What do I do?
