How much RAM? If you look at Activity Monitor, at the bottom under System Memory, now man page outs and how many page ins? What happens if you don't use the neon fractal pattern screen saver?

4GB RAM. It's been rebooted since the problem so I'm not sure this is relevant but: 1.2GB free, 2.8GB used. Page ins: 630MB, Page Outs: 0
I quite like the fractal screensaver, but will turn it off and see if the problem still occurs. The only issue is it wont be a scientific test as its often sporadic and so does not always occur anyway.

Ok. Have a look at those Page outs/ins next time it happens. That is just one possible angle.
Also, if this were happening to me, I would note the time of day it happens next, then open up Console (Utilities folder) and review the system logs for that time to see if the computer says anything helpful about the cause.

Thanks. I'll keep this info handy and compare when it next happens.

You might try this.
Wakeup problems with Macbook Pro: Boot to Recovery drive (command - R). Run Disk Utility/Repair Permissions and Repair Disk. Reboot to startup disk. Hold down the option key while using the Finder "Go To Folder" command. Enter ~`/Library. Delete Cache folder and Cookies folder. Empty trash.

Thanks Eric. Not sure I'm comfortable with Booting to recovery drive, or Rebooting to startup disk. I muddle through technical stuff. I'd kick myself if I ended up destroying all my data and media files by doing something with the inner workings.
What should I expect from the reboot options you mentioned?
I dont mind running some sort of cache cleaner and emptying trash, and have tried this before.

Do you have a backup, like Time Machine or a clone program? If not, you should. If you do have one, backup before doing anything. Then if something does go wrong, you won't lose any data.
This discussion is where I got the instructions I posted above. Apple tech support is who recommended this fix.
Booting into the Recovery mode is merely booting into a partition which Mountain Lion created on your hard drive or it will take you to an Internet site which give you the same options. Once there you will see an option to reinstall the OS, recover from Time Machine, and Disk Utilities (there may be more). This article talks about the recovery mode. You can basically ignore what is there because it isn't what needs to be done.
Select Disk Utility and run Repair Permissions a couple of times. Then run Repair disk to make sure your hard drive is okay.
Once you have done that, restart without holding down any keys - it is a normal startup.
Then finish the rest of the instructions.
What this does is removes old, possibly corrupt files, that are slowing your wakeup.

Months ago, after updating to latest OSX, my early 2011 Macbook Pro developed the 'slowness after screen saver' problem. I un-ticked screen saver and just used screen sleep settings and hard disk sleep settings. No problem with slowness after a reboot.
Then, just this week, I enabled screen saver again, just to check. Same issue: Mac slow to wake up and slow for a while in most or all tasks after that. Reboot fixes it.
My guess is, there is some OSX glitch with screen saver affecting Macbook Pros of the age of mine and maybe others too. Indeed, maybe many.
It really should have been fixed by now, one would think.
