OK, disk speed should not be a problem. It now sounds like the machine might be CPU-bound somehow. If you can then please:
1. Open a Terminal window and run:
top -d30
2. Launch programs and reproduce the bug.
3. Within 30 seconds switch to the Terminal window and see what's using the most CPU. Take a screenshot.
4. Wait another 30 seconds for 'top' list to change and again see what's using the most CPU. Take another screenshot.
5. Attach the screenshots to this bug.
