Is someone else seeing this?

F7t4# hdparm -tT /dev/sda

/dev/sda:
Timing cached reads:   2206 MB in  2.00 seconds = 1104.24 MB/sec
Timing buffered disk reads:  102 MB in  3.03 seconds =  33.68 MB/sec

FC6# hdparm -tT /dev/hda

/dev/hda:
Timing cached reads:   4576 MB in  2.00 seconds = 2290.99 MB/sec
Timing buffered disk reads:  102 MB in  3.01 seconds =  33.86 MB/sec

Is this a real problem?

the kernel has debug features enabled (see test4 release notes) they could  be the reason for this.
