MBP speed issues

Hi
I have a base 13'' mid 2012 mbp that I use as my main (and only) computer. Sometimes I feel it's getting slow and was thinking of changing my ram from 4gb to 8gb but by looking at activity monitor, the graph is all green that should indicate that ram is enough.
By looking at these stats, what is the reason it's slowing down?
Thanks

It could be hard drive related. What are you doing when you feel it is slow?

My main usage is for internet browsing (using chrome), I experience speed issues when I have lot's of chrome windows opened, for example switching from a tab to another, or switching to chrome-->itunes-->chrome, frequently it freezes the OS or the colored ball appears

It's sounding even more like a hard drive issue.

Sounds more like a chrome issue to me. OP specifically mentioned that it occurs when there's a lot of tabs open in Chrome, and also when the OP switches between Chrome and iTunes. The fact that it happens independently of iTunes means it's not an issue there, and the fact that it happens only under certain conditions effectively rules out a HDD/SSD issue. If it was a HDD/SSD issue, then it would most likely be seen outside of Chrome. Chrome is notorious for being a memory hog, and there's a lot of posts on these forums about that.

Your stats point to something you are running using lots of cpu, quite likely that is Chrome and your story supports this.

Try a different browser (I'd recommend Safari as Firefox is a resource hog in any case), and see if it still occurs.
