MORE THAN ANY other piece of software, iTunes is most likely to suck down 100 percent of my CPU and grind my work to a halt.
Yes, fanbois, iTunes sucks more of my W7 2.8 Ghz 8 GB RAM processor than the much-maligned Flash. And because I need my processor to work, not just run my laptop's fans as space heaters, I have taken charge of iTunes and started to aggressively figure out ways to minimise its use. This is a challenge for me because I've used iTunes as far back as I can remember with an iPod that I got for Christmas 2003 and with a dozen devices in between. Repeated syncs, multiple iTunes accounts, and disparate forms of digital media have often confused iTunes to the point where more than 500 tracks are unfound whenever I sync. The tracks are in the folder iTunes uses to keep my earbuds happy but iTunes cannot figure out the tracks.
And worse, iTunes won't recognise my iPod Touch so I couldn't upgrade it to iOS 5 until I did a few things below the break.
