"Overclocking" for Adobe Photoshop

I suggest "overclocking" the speed of your photoshop:
1. Set the optimal values ​​for the History states (= 20) and Cache Levels (= 6) in the Edit> Preferences> Performance menu (or Edit> Preferences> Image Cache for Photoshop CS2). This is necessary for faster work with large images (from 5 megapixels and above), because the default values ​​are more suitable for small images. At the same time, remember that the number of saved history steps was reduced to 20 ! Use non-destructive methods (Adjustment layers), or simply duplicate the layer before doing anything destructive.
2. If you have MORE THAN 1GB of RAM, I recommend enabling Plug-In Bigger Tiles which is also oriented to work with large images, and is disabled by default in Photoshop! You can enable it like this: in the Photoshop \ Plug-Ins \ Adobe Photoshop Only \ Extensions \ Bigger Tiles folder, remove the ~ sign in the file name ~ Bigger Tiles.8BX so that it becomes Bigger Tiles.8BX. That's all!
PS Do not forget to restart Photoshop after each of the above manipulations.
