Hello, Given all the discussion around SSE[2] lately, I was curious as to whether we had made any plans to update Windows users that are running 32-bit Windows builds on a 64-bit Windows OS to our 64-bit Windows builds. The 64-bit Windows builds do use SSE2, since that's a baseline requirement for x86-64 processors, and the overall performance should generally be better (modulo memory usage, I'm not sure if we have an exact comparison). Additionally 64-bit builds are much less likely to encounter OOM crashes due to address space fragmentation since they have a very large address space compared to the maximum 4GB available to the 32-bit builds.
It does seem like we'd need some minimal checking here, obviously first for whether the user is running 64-bit Windows, but also possibly whether they use 32-bit plugins (until such time as we unsupport NPAPI). 32-bit plugins will not work on a 64-bit Windows Firefox (we do not have the equivalent of Universal binaries like we do on OS X). -Ted _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
