Mountain Lion slows down my iMac

Mountain Lion slows down my iMac .


iMac 27 inch late 2009


3.06 GHz intel core 2 Duo


My computer was working really well despite its age until I installed the new Mountain Lion.


Now I find that it is much slower .


The main problem is between stiching from one programme or another I get the spinning wheel for maybe 10-15 seconds,

even switching between tabs in web browser .


Any genius to help with this problem ¿?¿?¿??¿



Thank you .

iMac, Mac OS 8.6 or Earlier

Excellent work by mende1.


I've just installed Mountain Lion because I needed an upgrade but didn't want Mavericks with all the problems it seems to have a the moment.


I repaired permissions then dragged all of the sub folders in the Libraries/cache folder to the trash.


After that I shut down the iMac and powered it up again.


Now my iMac seems if anything to be a little faster than with Snow Leopard.


Great advice.
