Have you ever heard about the command
purge? Hmmm, never heard about it? Well, that’s means you are view the right page.
Let me change the question.
Have you ever met a situation like this?
Holy shit, 8GB DDR3 memory is still not enough?
Most of the time, I will blame my default browser: chrome! Usually, when I quit chrome, it will free 3GB+ memory, and my Lion system will go smoothly again.
But, chrome is not always the reason of high consumption of my physical memory. I don’t know which one is using a huge bunch of memory then leave it as INACTIVE, just as figure 1 looks like. The blue pie is huge! and the most important thing is it is INACTIVE.
purge comes to rescue, open your terminal, then type:
BOOOOM! my system looks like as below, and feels much more faster!
The story behind the scene is relatively complicated, you can read Apple’s document. But anyway, it’s a shortcut to free your valuable INACTIVE memory.
