When I have a folder full of images and let Bridge create thumbnails after a few minutes all the system memory is used by Bridge and the system become very very low.
I even tried tu upgrade system memory to 8GB but the problem is always here.
Do you know how to fix it?
Bridge is more of a processor hog than memory hog. When building the cache it can take a long time if you have a lot of images. When it is doing this process it can result in a very slow computer. Once built you should be fine. If you have to rebuild all the cache some let it do this overnight.
