Hi, thanks Martin for the performance runs. It seems that although some runs show significant improvements there are occasions where you would choose 32bit.
In the discussions it seems that a switch for choosing between 32bit and 64bit is wanted. We have not found any good way, that will work for all installations, how to set up a SMF property that comes with different default based on the platform you are running on.(Anyway, we are open for suggestions :) We would also argue that to get the most performance out of MySQL you should also tweak the settings in my.cnf as well as choosing the binary that works best for the purpose. So having a property makes us choose the default as 32bit. I have updated the the ARC case with the comments: http://wikis.sun.com/display/WebStack/MySQL64bitARC Updates are: -the connectors are placed in separate location -update for the enable_64bit property -added documentation changes -renamed the packages -added file listing Regards, Jan S Martin MC Brown wrote: > Hi Everybody, > >> I'll do similar Studio12 builds over the weekend and re-run as well. > > > OK, I ran the tests (and experienced a problem on my x86 host for 64-bit > builds), but managed to get together some good results which I > summarized here: http://coalface.mcslp.com/?p=68 > > The upshot? > > Basically on x86 there seems to be a significant advantage of enabling > 64-bit builds over 32-bit.
