Hi Everyone,
I'm using bcache with a RAID1 pair of SSDs (for the cache) with a
MD-RAID10 spindle array for the backing device. On top of this is LVM.
This setup is used with the Xen Hypervisor. Bcache is formatted with a
sector size of 512 bytes.
If I use an LV for a Linux DomU, I get fantastic disk performance using
fio (about 23k random write). However, when I use IOMeter in a Windows
HVM DomU (with GPLPV drivers installed), my avg IOPS is around 4000. I
am using the "default" Access Specification. Am I doing something wrong?
Changing the number of workers doesn't seem to help.
Any advice is appreciated.
Thanks
