Depending on the how powerful your Pro Tools computer is then the time it takes for Pro Tools to launch can range from a few seconds to a few minutes.
If you are a Pro Tools veteran then you will know there's one thing you can do to reduce the wait, and that is remove any plug-ins you don't use and only keep the plug-ins you use in the Pro Tools plug-ins folder.
If you have ever installed Pro Tools from fresh and launched it before installing any 3rd party plug-ins then you will see how fast it is to launch, that's because it is not loading those plug-ins. As time goes on and we install our 3rd party plug-ins, free Pro Tools plug-ins, demos, bundles et al then we go from having around 50 Pro Tools plug-ins to 500, most of them not used.
So if you want to declutter your plug-ins from your Pro Tools system then simply move them to the unused plug-ins folder. Avid have a handy guide to show where to find you Pro Tools plug-ins folder on both Mac and Windows.
It takes a couple of minutes to declutter but it will help speed up your Pro Tools start up time.
