Why is my PSP Slow?

Well , there are many causes of that problem , here are the examples :


-You have too much files running or in your memory stick.
-
 Your memory stick could be fake. 
( I tested this I have 8GB real and 8GB fake. I have the same files in those 2 memory sticks. and the fake is slower than the real.)


-You are running many effects like CXMB themes (with many effects and designs.)


-Some firmwares lag. (Faster is M33 and GEN CFW ) ( Slow are 6.xx and above) ( Mostly PRO CFW lag in RemoteJoylite)
