I am running on Macbook with 2.4GHz Core 2 Duo processor, 4GB DDR3 RAM, Lion OS X 10.8.4. Last weeks I have noticed that the work with it is so slow, for example browsers.

Doesn't matter whether I use Google Chrome or Safari, bot in bot cases when I click on the new tab, I see the rolling colourful circle and in 2-4 seconds is displayed the new tab and I can type an URL address.

This makes the work with this machine incredibly slow. I checked if in the background is not running disc indexing, but it doesn't.

Had anyone the same or similar issue? How could I fix this behavior and speed up my MBP? What software to use for cleaning up the MBP?

Thank you

Does this happen everytime or only sometimes (e.g. after many hours/days since boot) ? What about RAM availibility (free, not inactive) ? and disk usage (in percentage) ? – dezzeus Jun 29 '13 at 16:03

One thing that can slow down your MBP is you might have too little space left. Try free up some space might help.

You will get a lot more performance if you upgrade your RAM since you only have 4GB.
