system test

[Alvin Oga <aoga@Maggie.Linux-Consulting.com>]

hi ya

- i just did a random tst for 24hrs

- for those looking to "tweek" the maximum performace out of the disks

- all systems are indentical - asus a7m266-vm motherboard
- 4 of the systems are amd xp-1700, one each of xp-1800 and xp-1900
- all systems are 512MB DDR except first one
- all tests were done simulataneously.. one machine next to the other

test was:
	cd /tmp/Test ; rm -rf linux-2.4.19
	cd /usr/src ; tar cf - linux-2.4.19/* | \
		( cd /tmp/Test ; tar xvfp - )
	make ; make dep ; make bzImage
	print number of passes

3 surprises...
	- use ata-133 disks
	- add more memory :-)
	- set -u1 and -c3 on the hard disks :-)

if the differences of 5 or 10 kernel compiles doesnt make a difference,
than its not an issue... but it "takes a while" to go thru 10 passes
of kernel compiles ( say about 30min - an hour )
	- yes... but its $10 or $20 more to just buy an XP-1800

have fun
alvin

first number is the number of kernel compiles (over the 24hr period )

2nd system was slightly modified, making it perform  like an xp-1800
system:-) 
	hdparm -tT /dev/hda  to get default MB/sec transfers
	hdparm -c3 -u1 -d 1 /dev/hda1
