Applications Loading SLOW under OSX 10.2.3

All,

I have a Powerbook G3 550Mhz (Firewire/Prismo) with 1 Gig of RAM. I have just "upgraded" it to OSX 10.2.3 from OS9. I completely reformatted the drive and then created a HFS (I believe) partition on which I proceeded to install OSX. This system is a part of a small windows/macintosh network. Appletalk has been turned off and only TCP/IP is being used as a network protocol. This Mac is primarily being used for some DTP applications, AOL and MS Office X. Norton Anti Virus 9 has been installed. All applications installed are fully OSX compliant. Now the application are running extremely slow(compared to OS9), even though it has 1 gig of ram. Under OS9 it had only 256mb of RAM. After some research on this wonderful form (wink), I have taken the following steps to further troubleshoot/resolve the "slowness":

1. I have made sure that "Net Info" is unchecked under Applications>Utilities>Directory Access.

2. I have also gone into Apple-S (single user mode) and ran FSCK -Y.

Please Help

Thanks in Advance

OK--here are a few responses to some of youe question(s):

Slow meaning 10-20 seconds for the app to launch.

Axing norton will try that but...

Also Updating to 10.2.8 for the sake of updating is maybe a solution. I mean what has 10.2.8 fixed?(not sure myself) and I can't be the only one who has had this slowness. I will also try and post the exact list of all the processes running.

Thanks

Thanks Wes that did the trick!!!!!!!!!!!

Can anyone explain/point me in the right direction where I may find more explanation(s) to this problem(s)
