Which is better on a low-memory machine: 32 or 64 bit?
I have a moderately old laptop, with an AMD Turion 64 X2 TL-50 processor and 438 MB RAM (after the graphics takes a fair old chunk it seems). I've currently got lubuntu 64-bit on it, and am not 100% happy with the performance. (Though I'm very pleased with the system in other respects). I'm wondering whether 32-bit GNU/Linux might use less RAM, and thus result in better performance.
Or should I be more focussed on other things if I'm looking to boost performance, like maybe the hard drive, or stopping the CPU throttling down (/proc/cpuinfo reports 800MHz)?
