Memory Usage.

Good afternoon. Raise the old question of resources consumed.
SS uses 800-1GB of memory and 15-25% of the CPU. (Win 7 x64, Phenom II 4 cores 3.7ghz, 8GB ram) This program is quite slow.
It was the introduction. Here's my version of how to deal with:

Many people probably know about the Game Booster. In his settings, there is an item "clear memory". After running the memory used by the SS drops to 100 megabytes, and then again begins to rise up to 1GB (within 30-60 seconds), but it proves that all subsequent program memory is not actually used. I'm not very versed in this, but apparently the program does not clean up resources used after multiple requests to download and search. Share is very big and swing with me a lot.
As Nir can say about this. It really is a problem with resources? and can you fix it?
