Project Mercury is a tiny portable tool which tries to improve performance when you're running many applications at once.

The program works by automatically increasing the process priority of the active application, which tells Windows to give it a greater share of CPU time, then dropping priority when the application is minimized.

Project Mercury offers various other tweaks which might boost speeds in some situations - disabling Hyper-Threading, Core Parking - but could also slow you down. Most of the options have no documentation, either, so they need to be treated with care.

The program also has a bonus memory cleaner-type feature which frees up RAM when minimizing an application, or on demand. This rarely makes much difference to performance, but you can try it and see.
