Photoshop required large memory to function well, preferably 1 GB or more. Each time Photoshop start, all plug-ins (necessary or unnecessary) also load with Photoshop. You can prevent unnecessary plug-ins from loading on start up, so that you can significantly decreases the time it takes to load Adobe Photoshop.

You can do this manually or more easily with the software ‘Adobe Photoshop SpeedUp’. To do this manually, navigate to C:\program files (assuming ‘C’ is your installed directory)\Adobe. Open the directory. Here you can see folder named ‘plug-ins’. Within this folder you find the plug in file folders, all of which loaded each time Photoshop started.

You can disable plug-ins which you scarcely use. To do this simply edits the name of the files or folders containing plug-ins and insert a tilde (~) before each name. You can always re-enable the plug-ins by deleting the symbol ‘~’.

By using Adobe Photoshop SpeedUp software you can do this quite easily. Just clicking a button, you can disable or enable the plug-ins. There are several options such as whether to load the Adobe fonts, load the presets, and set the memory usage. You may restore to the original settings at any time by clicking a button.

Adobe Photoshop SpeedUp is freeware, works with Adobe Photoshop versions 3 through 8.
