I used to do the same, recently I switched to MacVim. I found using Vim in Terminal/iTerm2 slowed down drastically after I worked with it for 10-15 minutes. Opening a file would take 1-1.5s, compared to MacVim which was instantaneous. I thought it was tied to a plugin, tried going barebones and still the same problem. (Although removing vim-rails sped it up a tiny bit.) Unable to diagnose it any further, I had to switch to MacVim. Anyone else had similar problems and managed to resolve?
