Macbook pro too slow

my macbook pro 2011 is very slow.......i download movies , use aperture, firefox, itunes, chat, etc nothing else but my book is too slow... it always hang up and every ove take atleast 5-10 seconds........
here is my mac configuration

macbook pro (march 2011)
Processor 2,3 GHz Intel Core i7 (quad core)
Memory 8 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6750M 1024 MB
Software Mac OS X Lion 10.7 (11A511)
500 gb sata disk

please help.....

What hard drive do you have? Is it the 5400 RPM drive? If it is Apeture, movie downloads, and iTunes (doing something) could be hitting the drive harder than it can react - thus slowing everything down.

Also - try installing the 10.7.1 patch from the software update under the apple menu.

Lastly - this should probably be in the Apple Notebook forum - rumors and reports is for news about Apple.

thats weird well try to quit some apps that take up a lot of space maybe. also your lucky you have i7 i have a macbook pro 13 inch i5 with 8gb of ram. I hate how our 2011 models overheat!

thanks for the help i shall do so,,, i have a 500 gb sata disk

Yes but the 500GB comes in 7200RPM and 5400RPM flavor. I believe the 5400RPM 500GB is the default - so if you didn't upgrade the hard drive you probably have a 5400RPM drive.

You can see it in Apple -> About This Mac -> More Info -> System Report -> under hardware -> serial-ata - it should show a dvd drive and your hard drive. My rotational speed says 7200 - so I have a 7200 RPM drive.

With the specs you have - anything running should be fast, if it seems to take a long time to save stuff, download stuff, start programs, boot, it is probably the hard drive.

You also may need to do some basic maintenance (i.e.: verify drive, repair permissions, etc.) as that may also be affecting performance (see the OSX software thread and the troubleshooting sticky)

Thread moved to more appropriate forum. Please read before posting in Rumors & Reports.
