Photoshop brushes question

Hallo~ I use photoshop, and I have a question about brushes. They're are so many pretty ones, but I don't download and use them often for a reason. Every time I try to view/scroll through my brushes, it lags and takes a while to let me see them, and even after I've scrolled and "loaded" through all of them, when I try to scroll the other way it still lags. ~_~ I have no idea if this is possible (so if it isn't, feel free to delete) but is there away to make it less lagsome? Thank you! ♥
