GDB reverse debugger is very slow as it is saving the execution state after every instruction executed.
There is a commercial plugin for GDB reverse debugger: UndoDB. It is much faster than just GDB (they claim only 1.7x slowdown), but unfortunately not very stable for the product I'm working on.
I'm a co-founder of the company. Lots of stability improvements over the past year or so: I'd urge you to try it again. Particularly v4 beta. Send email to beta@undo-software.com to get a beta license.
I'd never claim it's perfect: it's software after all, and the fact most software has bugs is why we have a business in the first place ;) But we're used by some pretty hardcore folk these days, including Cadence, NASA, and some of the biggest banks in the world. And the PyPy guys seem pretty happy :) Oh, and of course, if you do find issues, please do report them to support@undo-software.com -- then we can fix them.
