ghacks compares 32-bit and 64-bit browser versions

[mouser]

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.
