Currently, cpbackup says "waiting for load to go down to continue" when the load goes over "1". Now that i've got quite a few accounts on the server, its taking forever to run cpbackup every night. Is there a way to raise this limit to 2 or 3 to get backups done faster?

I'm pretty sure this is set in:

WHM > Tweak Settings > Stats and Logs heading > The load average above the number of cpus at which logs file processing should be suspended (default 0)

ok, i'll give that a try. thanks
