Whenever I boot up Premiere Pro, it always has to load up all of my files in my project before I can do anything (when it's finished it'll say All media loaded in the bottom left).
I don't remember it doing this before. Anyone have any experience with this??
(I'm not talking about waiting for PP to startup, this is waiting when I already opened my project)
This is normal. It happens for everyone.
Right. You may not notice it with small and new projects. But, the larger your project grows, with more items in your timeline, the longer it takes.
A large part of this time is taken by loading the .pek files, which are the visual representations of your audio waveforms.
If you have a striped RAID on your system, you can speed up the process by assigning your caches preference to a folder on your RAID. Since striped RAIDs read and write faster than most commonly used single-disk boot drives (which I believe is the default location), that'll give you a slight speed boost.
