ghacks compares 32-bit and 64-bit browser versions


Nice article on ghacks today comparing the performance of 32-bit vs 64-bit versions of browsers:

Take home message: They perform identically, no advantage of one over the other.

"Verdict: Results are quite surprising, not only because of the hangs and freezes experienced during benchmarks, but also because of the performance parity between 32-bit and 64-bit versions of the same browser. Most differences are marginal and not visible to the user sitting in front of the device."

Solid summary.  :)

Humm, 64bit firefox feels somewhat snappier for me, with less hangs - but that might be placebo.

A 64bit browser should(!) have better exploit mitigation because of a larger address space for ASLR - it can be messed up if an application uses DLLs that haven't been properly compiled, and I haven't investigated if that's the case with firefoxie.
