I recently updated my 2008 MB Pro (2 GB RAM) to Yosemite from 10.6 and I've found that it's often unusably slow. After keeping an eye on Activity Monitor over a couple weeks, I notice that the Image Capture Extension and software updated processes are often using over 400MB of RAM, 95% of which is compressed.
Quitting the processes seems to make the system more responsive, but I assume that these are supposed to be running in the background.
The only applications I usually have running are Safari/Chrome, Textmate and LibreOffice. I've been closing app's from the bar when I'm not using them.
Are there any settings I can tweak to change this behaviour? Could it be a bug? (I've noticed similar complaints elsewhere online)
- I have a relatively large iPhoto library, but I don't leave the program running
- No peripherals (usb keys, cameras, storage, etc) are physically connected
I did a firmware restart several weeks ago and the Image Capture Extension has been behaving so far. softwareupdated continues to have high memory demand, the process regularly ends up with 400+MB of compressed memory. I suspect that at least some of my problems are related to (un)gzip constantly running.
