At work today, I did some "time trials" between the 2.03's and the 2.41's on an nForce 220D system with an IDE drive, and also on my own SCSI-equipped system.
Test: do a timed on-demand virus scan of 738Mb of data comprising 17900+ files. This is my administrative installation point for Office2000 Professional Disc 2 with SP3 pre-integrated, if you're curious what's getting scanned.
System 1
- Asus A7N266-VM
- AthlonXP 1800+
- 256Mb Crucial PC2100
- Maxtor 40Gb 7200rpm IDE drive
- Win2000 SP3+
Results, taken on second run:
With 2.03 drivers:
1m 48s
With 2.41 drivers:
1m 44s, or about 3.5% faster at the system level
Of course, my own system cleaned house...
System 2
- Asus A7N8X-Deluxe rev. 2
- AthlonXP 1700+
- 1024Mb Crucial PC2700 @ PC2100 speed (my third 512Mb module is out on loan
)
- Seagate Cheetah X15-36LP 15000rpm SCSI hard drive
- Windows2000 SP3+
Results, first run (data coming from hard drive):
With 2.03 drivers:
1m 09s
With 2.41 drivers, SW IDE driver installed:
1m 09s
Results, second run (data mostly cached in RAM now):
With 2.03 drivers:
0m 42s
With 2.41 drivers:
0m 42s
From these two sets of results, it seems like real-world system-level performance gets a little boost on nForce classic. My nForce2 system doesn't have an IDE hard drive in it, but what's notable is that my PCI SCSI adapter didn't suffer due to the installation of the SW IDE drivers. Maybe tomorrow I'll burn a couple of CDs on my IDE CD burner and see how it likes that, since that was the other sore spot for WinXP users who've had the SW IDE option in the past (an option now available to Win2000 users like me).
