Re: dump runs at ~ 4 MB pr. second using Fedora Core 2 instead of the ~ 33 MB pr. second I am used to from previous distributions !

supplimentary information:


disk + bus performance estimate:

    the disk dump writes to

bash-2.05b# /sbin/hdparm -tT /dev/hdb

/dev/hdb:
Timing buffer-cache reads:   1004 MB in  2.00 seconds = 500.82 MB/sec
Timing buffered disk reads:  124 MB in  3.02 seconds =  41.04 MB/sec


the two disks dump reads from

bash-2.05b# /sbin/hdparm -tT /dev/sda

/dev/sda:
Timing buffer-cache reads:   1004 MB in  2.00 seconds = 501.32 MB/sec
Timing buffered disk reads:  160 MB in  3.03 seconds =  52.88 MB/sec

bash-2.05b# /sbin/hdparm -tT /dev/hdc

/dev/hdc:
Timing buffer-cache reads:   1008 MB in  2.01 seconds = 502.57 MB/sec
Timing buffered disk reads:  116 MB in  3.04 seconds =  38.10 MB/sec
