slow

My Mac (Macbook Pro) is sometimes slow doing basic tasks, like browsing the web or something like that. If I open Activity Monitor, I have (maybe) one program that is about 10 % CPU, others are below 1 %. My CPU usage is not full. I still have more than 2 GB of free memory (out of 5 GB). There is no heavy I/O activity like copying files.

My open programs are Google Chrome (6 tabs, none of which are in some way (flash, many DOM objects, Javascript) have IMO, except maybe Gmail), Activity Monitor, Finder, Sublime Text 2 (text editor) and iTerm (terminal).

What is causing the slowdown? "Slow" being: taking time to write these characters (I press the keyboard keys but there is a delay before I see them on the screen), changing tabs or programs, etc.
