Hmmm I am not so sure about that.. because it appears the time it takes
compress files also slows down the transfer of them. I was getting like
6Mb/s from a server on the same switch as the backup machine. One CPU
out of 16 was pegged at a 100% under compression.
How do you know compression is the bottleneck ?
I happened to be watching htop at the time. I was suprrised to see only
one core pegged at 100%
That doesn't mean this process is busy only doing compression (it might, but it
could be doing something else)
Surely it would be
trivial to replace gzip with pigz and bzip2 with pbzip2?
BackupPC does not use an external binary to compress data so no, it wouldn't be
as trivial as s/gzip/pigz/
Oh? Then why is there a config variable for the gzip path ? What is it
used for it not compression?
Curious.
It's for compression of archives, not pooled files

You could always disable compression, and then see if it solves your CPU
issue....
