Yesterday, I wrote a follow-up to my initial post regarding my problems with freezes and kernel panics on my G5 Quad and the pain of having to run Mac OS X 10.4.7 on the G5 Quad with only the stock 512 MB of RAM, in order to determine whether I have one or more faulty RAM modules.
While last week I described the experience of trying to use Mac OS X 10.4.7 on the G5 Quad with only 512 MB of RAM as nearly unbearable, yesterday I explain that I was able to determine that the experience was much more bearable with the elimination of some third-party background utilities.
I also indicated that I would try to add these utilities back one by one, in the hope of possibly identifying one specific utility as the major culprit.
Well, over the past 24 hours I have had the opportunity to do just that, and I have indeed been able to identify a single culprit. And that culprit is LaunchBar.
The other utilities that I normally have running on my G5 Quad—Default Folder X, DragThing, and Butler—each contribute to the increased hard drive activity and overall sluggishness of the system running with only 512 MB of RAM. But it is most definitely LaunchBar that makes the experience go from sluggish to downright unbearable.
Now, it is quite probable that this is due in no small part to my particular LaunchBar configuration. Since I normally have a fast machine (a G5 Quad) with lots of RAM (4.5 GB), I have never been particularly careful about optimizing my LaunchBar configuration for performance. I have numerous items in my configuration that LaunchBar scans on a regular basis, and several of them are set to be scanned “automatically” by LaunchBar, which presumably means “every time there is a change.” This probably means that LaunchBar does a lot of indexing in the background. With 4.5 GB of RAM, I have never noticed any responsiveness problems. But with only 512 MB of RAM, LaunchBar—and consequently the entire system—in its current configuration becomes unusable.
If LaunchBar was absolutely vital to my daily work, I would probably spend some time trying to adjust the configuration so that the utility does not cause constant hard drive activity and the whole system remains sluggish, but usable. But honestly I don’t really have time for this. I am just going to leave LaunchBar off for a few days and use the rest of my system without it.
Don’t get me wrong: I love LaunchBar and I will definitely miss the convenient, user-centric approaches that it adds to my daily computing experience. But I can survive without it. If that’s what it takes to identify the real culprit in my system freezes and kernel panics (probably one or two faulty RAM modules), then so be it.
But I have to say that, without LaunchBar, the rest of the system is much more usable than I initially thought it would be. It’s definitely sluggish compared to the normal experience with 4.5 GB of RAM, but it’s not orders of magnitude slower, and it’s not nearly unusable as it was when I had LaunchBar running.
