Hey, does anyone have the issue of ram on 10.7.4? I was running 2 apps and the 4GB of Ram maxes out! I checked the Apple Support Forums and it seems to be a common problem, does anybody know if it will be solved in Mountain Lion?
What do you mean "maxes out?" Do you mean you're paging out?Hey, does anyone have the issue of ram on 10.7.4? I was running 2 apps and the 4GB of Ram maxes out! I checked the Apple Support Forums and it seems to be a common problem, does anybody know if it will be solved in Mountain Lion?
Purging free memory will only degrade performance, not improve it.As in the active memory becomes very high even with little to no apps open, to the point it freezes with the beachball. I have to use the app purge to fix this now
If an app needs more RAM, inactive memory is available to it, without the need to purge it.Purging will improve performance if you have one app that is needing more ram.
Inactive:
This information is in RAM but it is not actively being used, it was recently used.
For example, if you've been using Mail and then quit it, the RAM that Mail was using is marked as Inactive memory. Inactive memory is available for use by another application, just like Free memory. However, if you open Mail before its Inactive memory is used by a different application, Mail will open quicker because its Inactive memory is converted to Active memory, instead of loading it from the slower drive.
If an app needs more RAM, inactive memory is available to it, without the need to purge it.
Please re-read the instructions, including the bolded step #2 and try again.Here they are, this only started to happen.
I'm on 10.7.4
You still have about 1GB of memory available and you have a very small amount of page-outs, so you're not greatly exceeding your available RAM.Sorry. New here
I use Matlab extensively, I've never seen purge do any more than flush disk buffers (which is what it is supposed to do), which slows Matlab down. Purging is often voodoo.
GGJStudios is correct overall, and the vast majority of "complaints" are from people who do not understand how VM works in their OS (huge amounts of noise and very little signal when reading about this in forums). I've watched someone use a memory optimiser and say how much better having all the "green" RAM is, then see them just ignore the hang as they open a program, placebo effect of the worst kind...
However, there have been some more metered and knowledgeable claims that there is a bug in Lion, and Mountain Lion does include "virtual memory performance" as one of the new developer features, so until we get more details on what mountain lion may have fixed or improved, the question on a potential Lion bug is still somewhat in the air.
