Switch between tasks every Recommended: 60 minutes 255 minutes To reduce task 'swappiness'. That time is set to be long enough to allow most project tasks to run to completion without a swap. > * leave apps in memory (should default to No) > > Yes. ... Leave tasks in memory while suspended? Suspended tasks will consume swap space if 'yes' yes Not all tasks save their current state. Avoids rollback after a task swap. See the reduced swappiness above also. > * Checkpoint interval > > I have it set to 10 minutes. ... On a four core cpu system, I noticed very frequent disk activity. Hence I've set 10 minutes also: Tasks checkpoint to disk at most every 600 seconds Also, for a diskless system, I will use tmpfs in system RAM for the boinc directory and then run my own snapshot 'checkpointing' of the entire boinc directory using "rsync -c". Note the "-c" for the rsync: That does a checksum comparison to catch the files that appear to be updated in-place without the file modified timestamp being updated! The tmpfs-and-rsync avoids saturating the network... For such settings, have "presets" that then set all the settings according to common use scenarios?
