Maple Story lagging too much

It doesn't seem like it "only affects some people." Its more along the lines of certain maps will constantly leak memory or something. For a 100% instance for me, root abyss area won't leak nor will FM, however I will leak on any computer if I try to go to Cygnus Garden and fight the boss. Just don't misunderstand and don't mix up which maps did leak and walk to another map that didn't and try to relate them together.
