Just for grins and giggles...
[root@heorot root]# /sbin/hdparm -tT /dev/sda
/dev/sda:
Timing buffer-cache reads: 128 MB in 5.65 seconds =22.65 MB/sec
Timing buffered disk reads: 64 MB in 17.74 seconds = 3.61 MB/sec
This is on the following config (just for comparison):
PowerMac 9500/132
LinuxPPC 2000
144 MB RAM
NarrowSCSI 2 GB Seagate Barracuda HD
On-board Ethernet card
I generally get about 1 or 2 MB/s, depending on what I'm copying
(yes, I use TCP/IP). I'm running netatalk-1.4b2+asun2.1.3-7.
Just thought it would be fun to compare the two. Of course, the 9500
gets trounced by that monster of yours, but it's not too shabby... :-)
