Hi to everyone! First post, long time reader.. I've got a problem with my Macbook pro 13'' (mid 2011 4 gb ram 2,3 GHz i5): everytime is in delay: sometimes better sometimes worst. For example, i've got a typing delay and the same if i scroll a page with safari; also when i increase the volume or the brightness from the keyboard, the "logo" appears on the monitor after a while (1 or 2 or 3 second). And this with or without a lot of programs running. I'm not able to understand the reason. I had a look on "monitor activity" and the only thing that maybe looks strange is the wired memory that seems to be too high. Here is the monitor activity with no running programs: here is monitor activity with just a lot of safari pages opened: I would be really happy if somebody could help me. Thanks!!!
