问题
I've been trying to use Xcode 4 on my 1GB Mac Mini. It's not a happy situation. It frequently slows way down, presumably due to memory shortages.
Are there any settings I can change so it won't be such a memory hog?
回答1:
Another post here suggests that the problem may be having the "predictive compilation turned on in the Xcode preferences."
回答2:
I ended up doing the following. None of them reduced Xcode's memory consumption, but they did reduce the memory needed by other programs, and hence solved my problem -- speed is fine now.
- Start using chrome instead of Firefox
- Turn off spotlight and dashboard
- Don't auto-launch iTunes
