Hey guys, I have a computer with an AMD64 processor, but I run the 32 bit version of ubuntu for convienience. Though today, I got the 64bit feisty CD, and went and tested a few programs to see if they would be quicker.
I got some interesting results.
Oggenc, encoding a particular file on my 32bit install, takes around 21 seconds. Now, in the 64bit liveCD, oggenc encoded the same file in 14 seconds; an incredible performance increase.
But Lame, encoding this file on my 32bit install took 21 seconds, while on the 64bit liveCD it took 23 seconds... a performance decrease.
Does anyone know why this is?
