17916	2001-09-01 00:32:00	I have two very similar computers, one is a PIII 733 and the other is a Celeron 700. Both have 128MB RAM and run clean installations of Win 2000. The PIII has a 20GB hard drive and the Celeron a 12GB. Both drives are partitioned and the OS partition is formatted NTFS on both machines. These are new installations and there is very little data other than the OS on either computer as yet. The Celeron seems sluggish when opening programs or new windows and although both computers boot to the logon window in exactly the same time (1m 30sec) the hard drive on the PIII stops after another 30 sec but the Celeron machine grinds on for a further 1m 30sec. Where the problem really seems to show is when Norton AV runs a scheduled scan. Norton is configured exactly the same for both computers but the Celeron takes 36 minutes to scan 23,000 files while the PIII takes just 12 minutes to scan the same number. The difference seems too great to be written off as a difference between the two processors or the two HDD and I assume that there must be some configuration problem that is making the Celeron do a great deal more work than the PIII. Any ideas on what to check or any tests I could run would be appreciated. Regards Peter	Guest (0)

Right click on the task bar select 'Task Manager' and look at the performance tab which shows memory load and the processes tab that shows what is running.	Guest (0)

First, the 733 Pentium III is presumably the Coppermine variety, which means that it'll be considerably faster than the first generation PIII. However, in practical terms, there isn't so much difference in performance between a Celeron and a PIII Coppermine CPU. The Celeron does have a slower memory bus (66MHz as opposed to 100MHz) than the PIII, which makes a little bit of difference for some applications. You'll probably find that the Celeron's drive isn't as fast as the newer machine's, and that it uses a slower access mode as well. Are the graphics cards the same? That could make a big difference. You need to check that you have set up the Celeron system right. Do you have: * DMA enabled for the hard drive? * Is the hard drive set to the right DMA type (check in BIOS). * While in BIOS, refer to the motherboard manual and see if there are any performance-enhancing settings you could use. * Windows 2000 SP2 could be an idea -- it has support and drivers for much more hardware, as well as bug fixes. * Run Performance Monitor to see where the bottlenecks are -- is it the CPU, the memory, or the disk? -- Juha	Guest (0)
17920	2001-09-03 12:29:00	Hi I checked device manager 'view device by resource' option and found that there was no DMA driver installed on the Celeron machine. The DMA driver is installed on the PIII. Next question: How do I install a DMA driver. There was no obvious process/solution in device manager though I suppose the driver would be on the Win 2000 CD. I haven't had time to get into the BIOS to check the settings there and won't be able to do this for a couple of days anyway. Any advice? Peter	Guest (0)
