Why can “Program X” seemingly recover more RAM than Parabens Mem-Jolt?
Paraben’s Mem-Jolt tries to be pragmatic about its memory recovery. It doesn’t just arbitrarily toss things out of memory to meet your goal if that means dumping code and data you really should keep in memory, like parts of the kernel and so forth. While it would be possible to recover more memory at times, it proves detrimental to performance, so we strove to keep the heuristics on how to recover more conservative.
