Mac Loading folders slow?

Hi all, I regularly work with folders that are quite bulky in terms of number of files (about 5000) and size (the 5000 files together make up 2GB). These folders load pretty slowly (while other "normal" folders load normally). Is there any way around this? Some kind of setting, that it doesn't load all the files or something like that? Thanks!

 

Thanks guys. I think I've found a solution: I'm using "Commander One" now instead of Finder. Works like a train.
