He stated he had already installed Xcode tools. 😛
Yes, he did. But if you read the post I linked to you will see that the author makes a distinction between Xcode and the Developer tools.
I provided the link in case there was any steps he missed.
Freeing up memory like that is almost always a bad idea. I remember "memory purger" apps for Windows were all the rage a couple of years back.
OS X has very advanced memory optimizations, there's no need to be purging memory on a whim, it can cause even more slowdowns.
I have to disagree with you here.
The Purge command has allowed me to recover a respectable amount of RAM on a system with either limited RAM or a compromised external cache. I agree that OS X has good memory optimizations, but it will happily allow you to run out of RAM and lock up your system when using memory intensive apps.
Sometimes, quitting those apps to recover ram or rein in a process (such as TenFourFox gobbling ram) is not desired or an option. Forcing that ram to recover via the purge command is a useful alternative. There are downsides as Intell has mentioned, but you can either take the hit sometimes and suffer through some reduced speed to keep an app running or quit in the middle of something, or face a lockup.
Personally, as an example, if I'm low on ram, I'd rather take the slowdown hit in TenFourFox over restarting the damn thing and having to log back in to sites I'm already logged in to. T4FX is great, but it takes forever to load.
