MobaXterm is awesome. Except the performance is just crap. It's noticeably laggy doing basic things like opening tabs and stuff. Anytime it has to redraw/relayout it's just slow. And if you use RDP, the CPU just burns even when idle.

It's so promising though, I paid for it.

I paid for it as well :)

I pretty much use it mostly for ssh and have never noticed any lag. There are one or two oddities, but I can live with them. It's miles better than plain old PuTTY.

If I'm doing RDP I use RoyalTS, another thing I paid for because it does RDP management so well:

ssh has its own typing latency, doesn't feel like native to me

Can't say I've ever noticed any difference, even over the VPN to our stuff in the DC. Even serious vim editing sessions on a remote box with tmux feel just as instant as when I'm working on my local Fedora/KDE h/w PC in Konsole.
