iFreeMem... Free system memory for better application performance. A quick and easy alternative to either a reboot or RAM upgrade to get defragmented free memory.

If you are in the middle of using an application and the system becomes unresponsive for several seconds it could be the memory manager organising free memory for your application to use. IFreeMem clears Inactive memory to help your applications avoid the performance hit you get when running low on Free memory. You could think of it like a RAM upgrade.

Especially useful for users of memory hungry applications, i.e.:

There are plenty of free "apps" (if you could call something that just does the terminal command equivalent of "purge) that do the same thing. And you can just type "purge [Return]" in a terminal to get the same affect.

And then there is apparently some issue of some tracker that is installed with this software. It's the MacKeeper of RAM purger apps.

Do people still fall for this hoax software!?! Please save yourselves money and read why memory optimisation is a hoax.

This was written by the very well respected sysinternals and microsoft engineer for the windows VM manager and broadly applies as much to the darwin kernel VM.

While I haven't used this specific software, and thus can't comment on its effectiveness, the problem it is addressing, and the specific technique it is using are both real.

The problem - in Snow Leopard (possibly other versions), when Free Memory gets very low, the system becomes very unresponsive, even though there is lots of Inactive memory which should be able to made available very easily/quickly.

Many knowledgeable users (e.g. people with advanced degrees in computer science, like me) have observed this behavior, and suffered long-lasting beachballs.

A properly written VM "should" handle this better, but in this case there's clearly some problem, though there's some debate about what the VM is doing wrong.

But, freeing inactive memory (via purge or other means) does help the situation, at least temporarily.

Some people report better behavior in Lion, while some don't.

So, while your article is theoretically correct - using a third-party tool to manage memory should not be necessary or even helpful - in Snow Leopard, there's clearly some problem that other tools can help mitigate.

Thanks Tommy_b, I was just about to plunk down $16.25 for iFreeMem when I read your post warning that it sabotages purchasers’ privacy by installing the much loathed, privacy-challenged eSellerate purchaser identification framework without disclosing or announcing itself or asking permission. Well Activata, you just lost another sale for being too sneaky, chums. I hope you’ll take that lesson to heart and excoriate it from your wares.

That is because it is flushing inactive RAM to disk, and therefore you lose the cache the kernel carefully built up of recently used data. This software is junk, all it does is make more memory GREEN in activity monitor, at the expense of the kernel's carefully cached data.

here's some software from a japanese developer to free inactive memory on your mac. it's completely free and seems to work very well (no need to install developer tools). the webpage and readme files are in japanese but the apps are localized in english, italian and japanese.

http://tama-san.com/?page_id=2

--libera memory

for manual operation. just launch it and click on 'release'.

there's also a 'quit visible processes' option in the 'file' menu to quit all windowed processes. save your work if you plan to use it.

i translated a part of the readme and i figured out that if you rename the app from 'libera memory.app' to 'libera memory auto[1-9].app' (a number between 1 and 9 after 'auto'), when you launch it it will do a release the amount of times specified by that number and automatically quit, providing an automatic operation as long as it's launched.

--libera memory resident

for full automatic operation. after launching it, specify the time interval and the threshold value in mb, to check for inactive memory. after saving, and from what i understand from the readme file, it writes to ~/Library/Application Support/Libera Memory Resident/LiberaMemory.php for the saved settings and ~/Library/LaunchAgents/com.tama-san.LiberaMemoryLaunchd.plist to execute the settings without having the app open, through launchd.

you can also view a log in the 'file' menu.

Be sure to scroll down that page and download version 1.6.1 to get the features you just described. The earlier versions of the program are at the top of the page and lack these features.

if you watch the link i provided closely, libera memory resident is different from libera memory.

libera memory
1.6.1

libera memory resident
OSX 10.4 & 10.5 >> 1.1.1
OSX 10.6 >> 1.2.0

I've been using both libera memory and resident. They have a pretty light touch - sometimes freeing up to 50MB (maybe more), sometime hardly any, even when inactive memory is very high, and free memory is very low. Not using a lot of resources. Not sure what they're doing, but clearly not just running purge. Not clear yet whether they're doing enough to make enough of a difference to be useful, or whether I should just run purge when things get bad.

If anyone else has experience with them, please post.

@rufty tufty

despite i have no knowledge on how these things work, my guess is that libera memory does it the right way or, at least, in a non-aggressive way. from my experience it will only release inactive memory when the computer is idle and honor the system's own management but just execute it "sooner". if it doesn't release much or anything at all, it may be because it works in a safe way.

while nontroppo makes a good point about hoaxes and that os x already has a good memory management, there's also the third party application factor, which means not every app is perfectly coded and might allocate memory in a poor way, consume cpu cycles even when the computer is idle, etc, so os x might not cope in a timely manner to release inactive memory until the last minute and then you get beachballs, like you mentioned in your reply.

i might be wrong about it so, anyone, please feel free to correct me.

If Developer tools are installed, go to a Terminal window and type purge. The cost: FREE. There are free wrappers for the purge command ( I wrote one ).

Thank you Wayland Chin!
So they are getting $18 to put a GUI on the purge command?
Nice racket if you can get it.

And yet v3.0.0 is working fine for me under SnowLeopard. Don't know if I'll update.

Seems to work by dumping RAM contents to swap files. I ran this and now I have 6 swap files where before I had just the one! So the trade off is less RAM used but with more and slower swap files - can't see the benefit!!
