I’ve done a bit of cutting down on what I keep running on my Mac recently.

I used to keep lots of apps running all the time – email, Tweetie, Evernote, iTunes, Transmission, Google Chrome. All running, all the time, even overnight. Chrome always had a few tabs open – PigPog’s dashboard, Facebook, Google Reader, and usually a few things that I might decide to do something with at some point. It was a land of distractions, and things ground to a halt when I tried to run Aperture.

I installed iStat Menus, after reading about it in Smoking Apples. Aperture ran, and all my RAM was used. MacOS paged furiously out to disk, but couldn’t really keep up. Aperture would hang when building previews, sometimes for hours on end.

I tried closing almost everything else, but it didn’t help much.

I finally got around to testing the two 2Gb memory modules I’d removed when one became faulty, found out which one it was, and put the other back in. My Mac now had 3Gb rather than 2Gb.

I ran Aperture. It quickly used over 2Gb RAM all on its own, finished the processing it was doing, and shrank back down to around 200Mb. Just as it should. Looks like the problem was that with 2Gb of RAM, doing that just took a lot of paging in and out, and so, a lot of time.

By then, though, I’d taken a bit of a liking to having less stuff sitting open. I do quite like to see emails when they arrive (I don’t get many at home, so it’s not much of a distraction), but I don’t always need the Tweetie window there on show. iTunes doesn’t need to be running when my iPod isn’t actually syncing. Evernote doesn’t need to be running all the time, though it’s quicker to throw things into it if it is. Mail can at least be closed overnight.

As for the browser, I’m trying to make it a habit to leave it running, but with no windows actually open. That way, it’s very quick to start if I click a URL somewhere, or want to have a quick look at Facebook. The rest of the time, though, there’s no need to keep things open. I just need to check for any spams or comments on PigPog once or twice a day, and look at Facebook occasionally. Google Reader doesn’t need to be checked obsessively – just looked at sometimes. When I want to.

So far the results are good. I’m spending less time repeatedly checking the same sites and feeds several times an hour. The only problem is staring at the relatively blank screen, and wondering what to do next. I decided to write. I’m writing this now.

Producing some sort of output, rather than staring at Facebook and Twitter for an hour – sounds like an improvement to me.
