Hi,
i've just made a yum-update and updated kernel to
2.6.18-194.3.1.el5.028stab069.5
which gave me some really nice slowdown to USB 2.0 external drive:
[root@watcher ~]# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1948 MB in 2.00 seconds = 973.75 MB/sec
Timing buffered disk reads: 12 MB in 3.08 seconds = 3.90 MB/sec
so i get back to the
2.6.18-164.15.1.el5.028stab068.9
and got the speed back:
/dev/sda:
Timing cached reads: 1780 MB in 2.00 seconds = 889.09 MB/sec
Timing buffered disk reads: 50 MB in 3.04 seconds = 16.45 MB/sec
what could be problem?
