Hey guys,
I just instaled Tiger a week ago and to my suprise my computer seems to be running slower. Programs such iphoto, imovie, and iweb are running a bit slower thatn normal, but the real problem is finder. Its been buggy and slow ever since I installed tiger. Another problem is the fan. It is always spinning its fastest (again, since tiger), even now, when all I have open is safari, it is going nearly full blast. I am running on a first generation imac G5 1.8ghz, 1 gig of ram, and ilife 06 (installed before tiger, and it worked fine). Thanks for any help.

Did you do an Archive & Install or just an upgrade? Maybe something went wrong when you did. I recently upgraded my iMac G4 with 512 MB of RAM from 10.2.8 and to my great surprise, it actually sped things up!

Tiger is quite a bit more memory hungry than was 10.3.x or 10.2.x. As a result, many machines are slower running 10.4 than they were running 10.3.

For example, I have 1GB of RAM in my machine. Under 10.4, I need 4GB of RAM. Under 10.3, 2GB would have been fine. As a result, my machine feels a LOT slower under 10.4 than it did under 10.3.

To top it off, my hard drives are almost full, so I have some pretty serious fragmentation issues. I need a significantly larger hard drive to help prevent this from happening. All of this makes 10.4 slower than 10.3.

If you have enough RAM for what you do, and you aren't fighting with fragmentation issues, then 10.4 could very well be faster than 10.3. But 10.4 is the first version of OS X to not be definitively faster than its predecessor.
