| Great, probing questions.
Here is a bit more information
1. We upgrade in one of 2 ways. We either do netinstall from a netboot server for those where it is convenient or we copy a 10.8 install image to the computer and then have the teacher boot from that installer. The updates have been to 10.8.2 and then we've had them apply software update to 10.8.3. I don't know if the 10.8.2 machines see problems or not.
2. Computers are not all the same model. Most are Macbooks, some are Macbook Pro, and even a few iMacs. I haven't heard from all that we have updated that this is a problem either.
3. We've seen some interesting symptoms on most computers but we have no evidence that it is the cause or even related. For example, we have seen many who can not complete the Spotlight Index after the update. We've had to repair permission and delete spotlight preferences on these machines to get them to do it. We've also seen abnormally high memory usage in many of them (6 - 8 GB mem) at the time when this occurs.
4. One thing that is consistent is that, if you leave the machine alone the slowness will resolve itself in 10 - 20 minutes and then the machine acts normally for several hours (or perhaps a day or so) until it once again exhibits the problems.
I'm certainly open to suggestions!

Bart,
I am curious. How were your problem computers brought up to 10.8: upgrade or re-image? Have you tried applying a combo update? Are these users wireless or wired? I have no help to offer, just looking for patterns. We've upgraded a lot of computers to
10.8 and have not experienced reported problems along these lines, but I have a Lion computer I upgraded that does. Are your problem machines all a common model?
Regards,

We've been updating our machines to 10.8 over the past few weeks and have had numerous teachers all of a sudden experiencing sporadic slowness that is seriously affecting their ability to do their jobs. It does not happen all the time, but is very evident
when it happens……spinning beach ball, typing and nothing happens for several seconds, click to open and close and it takes 5 - 10 seconds to actually see the results….you get the idea. The worst problem is it affected my 27" iMac as well!
One thing that may or may not be related is the fact that many processes are being killed at this time (see paste below for a small snippet).
Is anyone else seeing this?
Does anyone have suggestions?
thanks
