Re: [Bacula-users] Copy Job performance issues

I can see no bottleneck at all ... but "status storage" still reports 40MB/s write performance.
So, bacula-sd read a block from source volume, then write it into destination volume, repeats until end of source volume.
This leads to about a half of expected throughput.
There was a thread on bacula-devel list about it: "slow copying from tape to tape."
At this thread Kern confirmed a possible improvement:
Yes, I am working on this now (a very low priority project for the moment) but
it will probably only be in the Enterprise version and not in the community
version.
