My 2009 imac (maxed out 8gb ram) is finally starting to get a bit creaky. I'm wondering if all the services I run today that I didn't two years ago, especially cloud and backup stuff like dropbox, google music, skydrive and crashplan are slowing things down in back. They don't have huge memory footprints (except google music, which occasionally just runs away and hangs with over 1gb taken), but my windows days remind me of all the little icons that would sneak into the taskbar. And anyhow, why does the mac force us to look at all these things? It bums me out in the first place. I know the app bartender can be helpful, but then given the slowdown lately I just worry about papering over all these little things running in my background.
