Slow start-up and loading

I’ve had Garry’s Mod for a while, and the initial startup has always been super slow. I thought this was just gmod, but my friends say its very fast. All my other source games have a very fast startup and load times, too. The actual In-Game playing is flawless; perfect everything. It’s just that loading that is slow. Can anybody help?

EDIT: Crap. This isn’t the help forum, is it?

Since its in the wrong forum. Might as well tell ya its probably all the addons and other things stored in your gmod directory.

Like the above user said, you’re best trying clearing your gmod folder out.

Thank you all, even if it is in the wrong forum.
