It may be a small amount of slow down but depending on what your server is used for, it may make a difference. Computing memory seems to depend on the program being used. Gkrellm in my opinion does it pretty good and accurate. Who knows which one is really accurate though. If all you have is a console, I would use top and take the amount of memory in use then deduct the buffers and cache. It may not be perfect though. Someone correct me if I am wrong here.
