I am working on a site that uses jQuery and has a fair amount of javascript that is run using $(document).ready(). On my dev machine everything runs great but it’s a pretty powerful machine. I have had reports from people using older hardware of behavior that seems strange and I am fairly convinced that it is down to the time taken to process this initial javascript on slower machines.
Clearly, the solution is to sort out this initial javascript but it got me wondering – does anyone know of a way to slow down the execution speed of javascript in either Chrome or Firefox to be able to simulate these slower clients on my dev machine?
Cheers!
Update:
Back when this question was posted, there weren’t the same set of tools that there are today. At that time the VM option was the best option therefore I am leaving it as the accepted answer. However these days I would go straight for Chrome dev tools instead as suggested by Oded Niv
This might not be the best solution, but something that could definetely work is to run a virtual machine, there you could specify all hardware specs as long as they are lower than you real machine.
