memTools Pro is now US$5.27 !

C'mon, make it a prefpane which keeps user-settings, and earn more stars.

ZO219  If RAM optimizers are a hoax, then what is this mystery substance that is released according to the thermometer graph on MenuMeters.

BACKPACKER  From the article mentioned below:

"As RAM optimizers force the available-memory counter up, they force other processes' data and code out of memory. Say that you're running Word, for example. As the optimizer forces the available-memory counter up, the text of open documents and the program code that was part of Word's working set before the optimization (and was therefore present in physical memory) must be reread from disk as you continue to edit your document. The performance degradation can be severe on servers because the file data that's cached in the standby list and in the System working set (as well as the code and data used by active server applications) might be discarded."

That's what iFreemem does since it only does manually activated 'deep' memory recycling.

From memTools' Help :

"Note try to avoid going too deep as it just causes potentially useful cache to be discarded and the MAC then has to re-cache various program caches. Try to use the least to do the job, and you will usually get incredible free memory performance."

I'm typing this from a 500MHz G3 iMac with 512MB of RAM memory and using memTools' Recycle By Time option (set closer to 'fast' for 300 sec. intervals). Firefox is noticeably smoother like this.

If only memTools was a preference-pane and remembered its user-settings, then maybe call it 'Pro' ;)

NONTROPPO  Mark Russinovich wrote a great article about how memory optimizers are hoaxes:

http://windowsitpro.com/article/articleid/41095/the-memory-optimization-hoax.html [1]

The home page uses technobabble to sound authoritative, but it seems to do exactly what all these hoax optimizers do, force active and inactive RAM page out of memory. The kernel is tuned to handle this most efficiently, applications like this just disrupt the memory manager's work.

Until the author provides proper technical information of how he is doing something innovative here instead of the technobabble of his homepage, this is snake oil and hoax, just as with Windows "memory managers". iFreeRam, another hoax app used to have "benchmarks" on his page showing how it really helped, his benchmarks were artificial and he eventually removed them as they were worthless.
