Hi, I have absolutely the same problem on my Dell laptop with Ubuntu 8.10, 64-bit (2.26.27-11) I used the same test to check the speed - encoding media file with "lame". The slowdown is about 4 times.
The good news is that I think I found why! (at least on 2 Dell laptops). The problem is in AC Adapter. When I use one with lower voltage then standard one. Here is how I reproduce this: 1. Start the system with standard (for my laptop) adapter - 90W. The system is fast. 2. Close the lid to suspend. 3. Change the adapter to 65W (you can do it with Dell, that is ok, just charge time is much longer) 4. Open the lid to return from suspend. 5. Now the system ~4x slower. 6. UNPLUG the 65W adapter to run on the battery power - and it is FAST again!! Plug 65W adapter back - and it is slow. I did few times - and it is definitely about adapter. Now the interesting thing about this that if I do full restart with 65W adapter - everything works fine! This quite annoying cause at work place we have lower voltage adapters and we need to restart OS every morning. Hope this will help to fix this bug.
