Well, I don't know if you'd call this a slow down or not. My system is a BP6 with 2xC366@550 (yes, I like collectables), deskstar, v3-2k, 64mb, win2k pro, CPUIdle pro, MBM 5.0, download accelerator, winamp, ie-oe5.5. No network; stand alone dial-up connection. Result: zonealarm eventually crippled my system. At first it was fine, just like on my nt box, then slowly one evening the day after I installed it, it just began to dig it's claws in until, slowly, nothing worked. Is that slow enough?
I was able to uninstall and 3 boots after that I'm back to normal.
Any ideas why this would happen? Any known issues with my other software?
