You are using the same connection for both? Are they networked?
The processors as to speed are quite similar. I don't think there should be a noticeable difference there.
However the RAM adds more confusion as the PII has only 128MB which is a very bare minimum for XP. The PIII has 256MB which is the official minimum for XP.
I would think the 128MB would be a problem.
The other point I was looking for was the hard drive ID in order to check the RPM.
What was the last line in the
Drives section of Belarc?
This is mine for example:
Maxtor 6Y060L0 [Hard drive] (61.49 GB) -- drive 0, s/n Y2S89MDE, rev YAR41VW0, SMART Status: Healthy
Also what are the exact models of Dell?
