I've still got several Win98 machines on my network. I'd say, on average, most of these machines are around 533MHz with 128MB RAM. I've noticed a considerable performance drop on these machines, and I've been racking my brain trying to figure out what is going on. I've noticed that when I disable McAfee 4.5.1, the performance improves dramatically. These machines do not have Internet access or email, so most of the extra options in McAfee (like email scanning, download scanning, Internet filtering, etc...) are disabled. Does anyone have any idea why McAfee would be killing the performance on these machines? (Besides the fact that McAfee is a resource hog to begin with) Any thing I can do to improve performance?
