If you use Textmate, you know that it automatically rescans every folder inside an open project to see if anything has changed.
If you have a folder with an extensive number of images for example, you can prevent Textmate from scanning and searching within that folder by right clicking on the folder and deleting the reference.
Please note, this folder will no longer be included in project searches. In order to save this settings you will have to click on File and Save Project As.
