2011 Update 3 Build 6942 Kills Machine Performance

Thread needs solution

Two or three days ago I downloaded and installed this update.

The effect was to make my machine virtually unusable. Boot times far exceed 5 minutes, keyboard and mouse response is nonexistent. (Fujitsu P1610 w. fast SSD, XP Tablet SP3. Other than running Dropbox, the configuration is fairly vanilla.)

All apps run slowly and unresponsively. Acronis 2011, already a slug, is noticeably even slower.

Task manager shows taskmgr.exe and vsmon.exe using a lot of CPU cycles.

Prior to doing this "upgrade" I had none of these problems.

It seems I can repair most of the damage by killing the "Acronis Nonstop Backup Service" and the "Acronis Scheduler 2 Service," but according to Autoruns there are several other Acronis modules that want to get loaded at boot time as well. I do not see these running in Task Manager, so I am guessing that killing the two services also shut these down.

Questions:

1) Is this a known problem? Is there a fix coming?

2) I run two scheduled backups a day. One image backup of my system drive C:\ and one file backup of my data drive D:\. I have no interest in online backup, continuous backup, or any other features. What is the minimum configuration of startup modules and services that I need to run in order for these two backups to be successful? The Scheduler, probably. Anything else?

The Acronis Sched service is the only one you need.
If you don't use the online backup, you can remove if from the installation process (I mean, you can when you install ATI, not afterwards).

If you do not use the Acronis sync function, you can also stop and disable the Aconris sync agent service.

Sorry to not respond sooner. I didn't realize that the default here was that I wouldn't be notified of responses.

Anyway, apologies to Acronis are in order. The problem was not with this software.

It's a subtle one, though: Apparently about the time I installed the upgrade, my SSD started throwing CRC errors at Windows. When this happens, Windows silently switches the disk access mode from DMA to PIO. This results in a huge hit to disk performance, as the CPU ("Programmed IO") gets involved in every transaction, instead of the disk controller independently dealing ("Direct Memory Access") with the transfers. As a computer designer by trade, I am astonished that Windows would make this switch without providing some indication to the user. No messages in the system logs, ... nothing!

So now I am off on a quest to deal with the disk controller and the disk. Prior to that, redownloading the Acronis package that I had uninstalled -- so I can back up the disk volumes!

Thanks, all.
