Is there some kind of optimal change time? Perhaps, some value is too low and the overheade of changing apps gets too high.

Keeping the paused application in memory can cause errors if there is no ECC-RAM in your computer. Swapping may also slow down BOINC work and other tasks if there is not plenty of RAM... ID: 22391 ·

I reduced the default time to 10 minutes to get smaller WUs out in time. Sometimes, a big WU like climatepredicition outrun small WUs. I wonder if there is a minimum checkpoint duration.

The "write to disk at most every xx seconds" option can be used for that. However, the science application does not need to follow it. ID: 22399 ·
