What vimrc settings to speed up scrolling?

I use gvim pretty heavily at work, typically logged into a server farm. This works great while I'm directly on the corporate LAN, but when I VPN in from home and resume my sessions, gvim scrolls almost intolerably slow.

Every time I page up or down, the scrolling does a lot of unnecessary scr开发者_JAVA百科een refreshes before it gets to the final spot.

I remember browsing other people's vimrc's and seeing a setting to help with this, but I don't remember what it is. I have ttyfast already set. Is there anything else?

I know this is mostly due to the VPN, but with a little tweaking, hopefully it can get better.

Another non-vimrc technique to consider is Windows Control Panel:
