Subject: Abysmal disk performance, how to debug?
Hi all,
I own a Sony Vaio VGN-FS285B and disk performance to say at least is very very
slow. Writing 1 GB data makes the laptop unresponsive. Here is some data
identifying the drive. Hope someone can tell me how to debug and find out
whats the problem.
FWIW since 2.6.16 the problem is same and I didn't test with 2.4 kernels. Here
is some data. And I tested with xfs & ext3. Both slow slow disk writes.
