I have 160gb out of 700gb (hardisk), 16gb of ram, and running moutain lion.

I use Disk Doctor and clean caches as well. It is not slow, just the rainbow round cursor appears quite often.

Rommendation needed.

I wonder my does my macbook pro is still laggy? 


Thank you. =)

    Cache files exist to make your Mac run faster.


    I use Disk Doctor ...


    Norton Disk Doctor? That piece of junk was discontinued ages ago. Get rid of it.


    Whatever you do, do not download or install any product claiming to "clean up" or "speed up" or "optimize" your Mac. Without exception, they will do the opposite. If you already did, you found the problem. Fix it.


    If you're experiencing general slowdowns or "freezes" unrelated to Internet activity, the problem may be related to your computer or the software you installed and is something you may be able to fix, or at least improve. Aside from hardware failures and software that you install, including OS upgrades, there is no reason that your computer should not work exactly as well as the day it was built.
