IFreeMem recovers memory for your applications to use and helps avoid the performance hit you get when running low on Free memory.
iFreeMem free’s memory from the in-memory cache that accumulates with every file or application read from hard-disk.
The cache is good, but it can become cluttered with files you don’t even need cached anymore that take up precious RAM.
Maximum free memory can sometimes be better than half your memory filled with old cached files.
