Awful Menu Lag!

I’m getting unbearable menu lag. Going from one menu item to another takes at least 5 seconds. Video playback stutters intermittently, too.

I’m running 2.3 and 3.4.2 barebones. Plugins are limited to nitoTV & ATV files. I did install the Tiger update to enable USB HDD support, and that’s it. The local drive is nearly full, but I fail to see the relevance.

I did have the same problem. I tried everything but didn’t seem to help. What I finally did that seemed to work was reformatting my drive using apple extended format. Only then the problem seemed to disappear. I think the delay is related to lag of reading from the Ext. HD. Seems that the drive needs to be periodically reserviced, either by re-formatting or doing a clean up.
