I recently installed backuppc on a smp fileserver, after having had good
success with backuppc on a different computer.
Backuppc is working normally, except I noticed it only uses one of the
two cpus. Even with two instances of BackupPC_Dump running, they are
both running on the same cpu and so top reports that the cpu is 50%
Is there a way to change this? I'm guessing this is a Perl
limitation. The fileserver is a little old - the cpus are Pentium Pros @
200Mhz. :-) So you can probably see why using the second cpu would be

Sorry, I thought that would be obvious when I mentioned top showing 50%
idle time on the cpu. I do have an smp kernel installed. "cat
/proc/cpuinfo" definitely shows both cpus and recognizes them properly.
There are other things on this server that use both cpus and the kernel
will start other processes on the idle cpu, but all of the Backuppc
stuff seems to be 'stuck' on the one cpu.
