iterm2, vim, tmux very slow in yosemite for anyone?

I installed Yosemite today and noticed significant lag in iterm2, vim, and tmux workflow. Anyone noticed this yet?

I’ve been using Yosemite beta for three weeks and upgraded to the release on Friday. I’ve noticed that Sparrow is occasionally so laggy that it’s unusable, but haven’t had any issues with iTerm2, vim, and tmux (all of which are part of my development workflow).

Have you spun up top or Activity Monitor to see what might be hogging the CPU?

Thanks Geoff,

I downloaded iterm2 nightly version and it is more stable. I don’t know, Yosemite seems little laggy with other apps as well. Opening safari with shortcut command is really slow. Thanks for the tip thought.
