[Xen-users] gplpv driver correctly supports 9GB RAM in Windows 32bit?
Hello
I have Debian Linux 2.6.32-5-xen-amd64 Xen 4.0.1, 2 SAS drives in
RAID 1, 16GB ram.
I have virtualized Windows 2003R2 32bit where you install the
latest version 0.11.0.295 gplpv
After reading and reading forums and post testing, I noticed that the
hard disk performance drops significantly when I assign the windows
domU 9GB ram. (below I leave the config files)
If I run the domU with 2GB of ram, I have 57% of performance in
reading compared with the Debian Linux (dom0). Translated into numbers
is Dom0 Read: 260.56MB/sec and dumU 150MB/sec.
If I run the domU with 9GB of RAM, I have 42% of performance in
reading compared with Debian Linux. (dom0). Translated into numbers is
Dom0 Read: 260.56MB/sec and dumU 110MB/sec.
These tests were done in windows1 and hard disk "''phy: /
dev/sdb2, hdd, w''"
This leads me to think I have some problems with windows1.cfg
options, such as SAP, ioemu, hap.
Or the low performance is associated with the need to map 32bit to 64bit?
I''m really confused on many parameters and do not know if the
combination of any of them is associated with low performance.
Using windows 2003 64bit technically is more optimistic? mapping
can influence both 32bit and 6
Thanks for being here.
I leave the files under configuration

(below I leave the config files)Why would you assign a 32-bit OS any more than 4GB? I''m not sure if that''s the problem, however I''ve never tried running 32bit windows with more than 4gig ram. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Standard edition 32bit is limited to 4GB ram. Only Enterpise and Datacenter support as far as I can tell (well, according to msdn.. which has been wrong in the past). _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
