A computer uses RAM, that’s what it does to make things faster. By forcing things out of RAM, your performance will suffer in other areas and may decrease overall system stability. The operating system shouldn’t push things out of RAM until it’s nearly 100% full, by design. An efficiently running operating system will be running at 90% full as often used files are cached, etc. I often work with servers with up-times of months. The RAM is usually quite full, it’s nothing to be concerned with.
This software sounds like it just wastes cycles doing something the operating system does better. IMHO, CPU cycles are worth more than RAM.
