Memory 'optimisers' were a fad on windows many years ago, and they were junk. Now they are popping up on the App store!Countless man-hours of hard work by computer scientists have honed the virtual memory systems of modern operating system kernels like Darwin, and this app just junks those caches to make it look like you have more free RAM.
Inactive RAM *is* usable RAM, so flushing your inactive RAM into "free" RAM doesn't give you "more" memory, it just makes more green in the pie chart in activity monitor. *BUT* inactive RAM does store information the OS X kernel may need again, so flushing it will slow down your kernel if it needs that info. Please google and read "The Memory-Optimization Hoax", an article written by the very well respected Sysinternals engineer Mark Russinovich.
