I am running OS X Lion 10.7.3 and Macvim runs significantly slower than vim on the terminal for me. All movement commands in Macvim are much slower. Moving up and down in visual mode is equally as laggy. I see none of this lag when using vim from the terminal. Does anyone know what the reasons may be? I am running NERDtree on every open tab, and I know this contributes some memory overhead and potentially some slow down; but even when I don't run NERDtree Macvim runs much slower than vim from the terminal. Any help in solving this would be greatly appreciated.
