Angry MacBook Air 2010 11" unbearably slow with ML

So what kind of experiences do you guys have that own the 2010 Air? I updated Mountain Lion some time ago and have to my machine has become unusably slow with ML. I even reinstalled the OS, but that didn't help. Browsing the internet seems to be too tough of a task for the computer. I perhaps could understand what is going if I had the 2 gb model, but I have 4 gigs. And I even upgraded the processor to 1.6 Ghz. The computer is just about two years old and I have to say I expected to get more out of this machine. I know this isn't a powerhouse, but things were just fine in Lion.

If 10.8.2 fix these issues I probably need to revert back to Lion, which would be too bad as my iMac runs ML just fine (well, it is an 2011 i7 so it should) and then I'd loose iCloud syncing.

This must be something specific to the install of your computer. I had Mountain Lion on a 2008 MacBook and it ran fine.

Check for updates and think about a clean install.

Not sure what the issue is. I have the exact same machine and things are working great on ML.

Mine was slow as well, but that was with heavy usage. One remote citrix session, multiple tabs in chrome, mail, some MS Office applications and Lync running. And it only had 2 GBs of ram. The 'lagging' or sluggishness was very apparent with fullscreen animations, and editing in iPhoto. But I felt it would speed up when I closed unused applications.

Repair your drive. Also, if you live near an Apple store, take it in and have them run some diagnostics.

I'd expect my SSD to be perfectly ok as it worked without issues in Lion. But yeah, I've tried repairing the disk and permissions. Also have reset PRAM and SMC. I'll probably wait until 10.8.2 as there are quite bit of people having issues with ML (freezing) and if that doesn't to the trick I'm going to go to Lion.

I actually tried Snow Leopard on a separate partition some time ago. It was great, so fast, so elegant and simple. No iCloud to manage etc. But times have gone past SL so many times that you really can't go back to it.

Nearest Apple store might be in Berlin or London. I'm at the arctic circle.

After a clean install, did you use Time Machine to restore all your stuff? If you did then this wrecks your nice clean install.

Obvious suggestion : Did you check Activity monitor ? What's the CPU usage at ? Do you have a runaway process or other background tasks affecting foreground performance ?

What's "slow", UI response is slow ? Window content rendering ? Just raw crunching of data ? Disk I/O, network I/O ?

"Slow" doesn't tell us squat about your experience. Activity Monitor will help you determine your bottleneck.

I have had no problems with my base 2010 13" (only 4 GB of RAM as an upgrade, otherwise running the 1.8 ghz base processor).

ML was a success on my 2010 11" Ultimate... it runs faster, smoother, and the battery life is still excellent.

I had an issue with my fans running full blast for a while after I installed ML on my 2010 11" (1.4/4/128), but things settled down nicely and now it's working fine without any issues. Maybe it's an application that you're using that isn't playing nicely with ML?

I experienced similar behaviour when upgrading to Lion- got everything back to working like a charm when installing Nvidia Cuda driver from Nvidia's homepage.
After upgrading to ML my Air felt sluggish as well - Nvidia drivers were outdated ... updated them to Version 5.x --> things went flying again

cheers

I have the exact problem. I updatet to ML on my Macbook Air 1.6Ghz 4 Gig ram. 128GB hd. 2010. Now its laging in Firefox. Its incredible slow. The CPU usage is not high on nay programs. The fan runs normaly. Have absolutely no idea what to do. It ran prefectly normal before the update.

Tonight I will try to"flash" NVRAM and PRAM. Long format. Clean install (again). Then I will come back with the result.

There is no reason that it should be "slower" with ML.

German site, but driver has always been international ;-) Should be downloading Version 5.0.24 ...
