I've had an iBook G4 14" 1.42GHz for a few years now (bought it about a month before they switched to Intel chips). I haven't treated it super-kindly (the day-to-day account is also the admin account, since I didn't realise you were meant to make yourself a limited user account; I've installed and uninstalled all sorts of software of varying quality; and I've made it a bittorrent packhorse for days at a time) and the battery was on the point of dying. I recently put a new battery in, and now that I'm not permanently tethered to the wall I'm enthused about fixing the machine up to get it as fast as possible.
I've been using the DAW Reaper
for a few months now and like it a lot. Unfortunately my computer isn't fast enough to do any audio effects work - every channel has to be clean or the program judders and overloads.
My goal for this project is to be able to use Reaper and Reason ReWired together for recording sketches in my bedroom. Nothing too ambitious - I'm not talking about running bitcrunchers, choruses and delays on dozens of channels - I'd just like the ability to use panning, compression and reverb on four or five tracks to make things sit nicely together.
So how do I squeeze out the speed? Will reinstalling the OS help? I've already got the maximum amount of RAM that this computer will hold. What processes run in the background that I don't need? Does the Quicksilver launcher eat up a lot of memory (I currently use it)? Would installing Leopard be a bunch faster, or would that money be better spent elsewhere? Can I tell the computer to prioritise one program at the expense of others? Should I set up a separate user account for recording that has almost everything disabled that isn't needed for ReapsonWire?
Aside from music making I'll be using this machine to cruise the internet, watch '.avi' files and write bits and pieces - so nothing too demanding.
Any and all tips considered. Thanks!
