Is any JavaScript engine faster with GCC than with MSVC? Most of the difference I've observed has come down to compiler quality on 32-bit Intel systems. I don't think Linux vs Windows has much to do with JavaScript performance.
- samstokes 16y agoI have definitely perceived Firefox to be slower on Linux than on Windows, particularly with Javascript-heavy apps. (Moreso in the days of 3.0 admittedly - I barely use Windows now anyway so I can't compare.) I was also under the impression that this was a common and widespread perception. I don't know exactly what's the cause of the slowness I perceive - whether it's the Javascript VM or the DOM implementation, or some interaction of those with something more plausibly platform-specific. I'm afraid I haven't tried recompiling Firefox with different compilers to test this!
