7 PCs of same make and model. Some slower than others.

These were bought in a large batch and they are all the same brand and model with same specs. I just re-imaged 7 of them with our latest image and while finalizing all the settings I notice 3 or 4 of them running slightly slower than the rest. The setup took a couple of minutes longer on them and navigating through Explorer and browsing a few sites on IE was just not as snappy as the others. On the slower ones you can definitely hear more disk thrashing but all machines have the same amount of memory.

Check the HDDs. Are they all the same brand and model#? There could also be slightly diffrent DIMMS of RAM in each system. Sure they are the same size but my have slightly differnt timings or use chips from differnt manufactures. There could be a number of subtal differances between them. Even down to differances in the various chips in each system. There are always slight variations in chips. No chip is ever the same. Its just the way things go durring manufacturing.

Power regulation will also be a factor. If you check incoming power under load, you may find differences. Are the power supplies the same make/model/rating? Is one older than another? Are the voltage settings in the bios all the same?

sounds like hard disk to me. start there (system -> device manager) before investigating the nuances of mass production minutiae. OEM's usually just list the size and spindle RPM on their builds and are liable to use all sorts of disk brands. even in the 90's IBM systems used non-IBM hard disks.
