10MiB/s is normal tap:aio:file.raw ?
Hi there
I am analyzing disk performance. I'm testing raw (tap: aio) and lvm (phy :).
The tests I'm doing on a SLES11SP3, cpu I7, 4GBRam, disco-SATAII 7200rpm.
With phy: lvm achievement 70-80MiB / s (an acceptable value)
With tap: aio: file.raw achievement 5-9MiB / s, which is very low ...
10MiB / s is what you should expect access to a tap: aio: file.raw? or I
have something
