Guest disk (LVM on SSD) too slow. Xen unstable, DomU-win XP sp2
nice time, Xen community.
my DomU has very slow Disk performance, despite the usage of SSD''s. Maybe somebody can give some good tips to accelerate, or point out my mistakes.
DomU CristalDiskMark 3.0.1 test(roundet):
seq (R/W) :71 / 86 MB/s
512k(R/W) :76 / 80 MB/s
4K(R/W) :4 / 3 MB/s
4K QD32(R/W):4 / 4 MB/s
The same guest running in KVM-Qemu (standard installed on Ubuntu 12.04) has:
seq (R/W) :319 / 146 MB/s
512k(R/W) :306 / 143 MB/s
4K(R/W) :10 / 7 MB/s
