disk diagnostics

["Pieter Dumon" <pieter.dumon@xxxxxxxxx>]

Hi,

how can I diagnose my disk read/write throughput under DFLy ?
my system runs well except that untarring even small tar files or
deleting files takes a lot of time (e.g. the removal of
/usr/obj/usr/src/world_i386 during a make buildworld takes about 25
minutes (I admit it's got a lot of files, but still....)).

I don't know if it can have anything to do with my strange
configuration of having the two harddisks on ATA1 while the CDs are on
ATA0. The disk with the DFly slice is only UDMA33 (there are no DFLy
slices on the other disk), but still, under windows and linux I don't
have this slow disk access.

ad3: 76319MB <WDC WD800BB-00JHC0> [155061/16/63] at ata1-slave UDMA100
acd0: DVD-R <AOPEN DUW1608/ARR> at ata0-master PIO4
acd1: CDROM <CD-ROM 36X/AKU> at ata0-slave PIO4

regards,
