Yep, you're right, even another 64MB will help keep swap from being used at all. It sure looks like you are completely CPU bound with the BackupPC_dump process, faster CPU may be all you can do to speed up backups, unless some profiling is done of the BackupPC_dump process to help figure out where the hot spots are and what (if anything) can be done to improve performance there. > > If logging in via ssh is sluggish, that does indicate memory pressure > > to me...

I would have expected to see higher I/O wait times if the sluggishness was coming completely from I/O competition, but if you're system disk is the same as the backuppc data partition then that sure doesn't help. -Dave ------------------------------------------------------------------------- Take Surveys.
