Hello,

I have a purely academic question stemming from an accidental install on my part: Will my AMD64 laptop run PD and other sound apps (using mingo's RT patched kernels) faster in native 64-bit linux or faster as a conventional 32-bit linux?

amd64 has a number of general-purpose registers that are not available in 32-bit mode, which means code compiled for 64bit will be faster regardless of whether it was specially optimized for 64bit, or uses >4gb of ram..the charts i saw at anandtech put it at around 10-25%..

I ask this because I am about to install the "correct" 64-bit linux but I will then have array problems and other PD errors that have not yet been solved... So if my machine is faster in 64 -bit linux the shortcommings of 64-bit PD are outweighed by the speed gain.

Thanks all! -thewade
