After updating successfully to 10.4.9 from a 10.4.8 JaS DVD install, the GUI became slow. When I click on the apple menu, I have to wait 1 or 2 seconds until the menu appears.
More over, (I don't know if these problems are linked together) Disk Utility doesn't want to repair permissions telling me there's "no valid packets" (I don't know if its the right translation, I use the system in french), and sometimes it doesn't log in at startup. I think I should have kept some kexts before updating but I don't.

Hoping it will change somthing I upgraded to 10.4.10 with the Koolkal installer (wich allow me to get the battery meter i was waiting for a long time, thanks a lot). But It didn't changed anything.
I also used XBench, I get less than 100 now, I got 120 under 10.4.8. I think the slowdown comes from memory but I'm not sure.

Can someone tell me if there's an other solution than completely re-install the system (again)?
Thank you
