06 Clear system & user caches

The benefit is that it can clear up some odd problems caused by corrupted entries in the cache.

The only real downside is some very slight slowdowns after the next restart as the system rebuilds the caches.

06 Clear system & user caches
Authored by: jlowrey on Jan 12, '04 10:25:58PM

Hello, I am the author of Panther Cache Cleaner. OS X and many of its applications use caching to improve performance. Occasionally, this cached data can go stale which results in odd behavior. Cache cleaning is very effective at fixing these types of problems.

However, cache cleaning is not without its risks. Caches can get quite large and consist of hundreds or thousands of files. It is critically important to check and repair any file system problems before deleting the caches. If there is unrepaired directory damage - particularly cross linked files - cache cleaning can create more problems than it solves.

On a healthy filesystem, cache cleaning is a very effective troubleshooting tool. Just remember to check your file system first.

And finally, thanks to Petey for a very nice list.
