Hi,
after applying
/usr/bin/psql -d bareos -c "REINDEX DATABASE bareos"
/usr/bin/psql -d bareos -c "VACUUM"
/usr/bin/psql -d bareos -c "ANALYZE"
as user postgres, I now get
bareos-sd JobId 58569: Despooling elapsed time = 00:03:28, Transfer
rate = 303.3 M Bytes/second
again.
@Chris: Can you confirm this? Please take care you have enough space,
reindex will take about twice the space you had before....
Regards,
Dennis

Interesting point, here are my numbers:

bareos-sd JobId 45943: Despooling elapsed time = 00:09:12, Transfer
rate = 213.0 M Bytes/second
_/Last three Incremental jobs after upgrade to 17.2.4 on 02.01.2018:/_
bareos-sd JobId 58397: Despooling elapsed time = 00:04:59, Transfer
rate = 174.5 M Bytes/second
bareos-sd JobId 58227: Despooling elapsed time = 00:12:03, Transfer
rate = 181.3 M Bytes/second
bareos-sd JobId 55354: Despooling elapsed time = 00:08:18, Transfer
rate = 155.1 M Bytes/second
So indeed it seems to got slower.
Where there differences between the RC and the release?
After installation of RC I noticed a slow database, so I ran ANALYSE
and VACUUM to postgres mainly because bareos-webui was unusable slow....

Dennis

I have no explanation for this. The changes done to bareos should no
have affected this. If have been database performance improvements mostly.
Has anybody else made similar experiences after upgrading to bareos-17.2.4?

I re-ran the update script and tried again with no change. It look like
despooling speed took the greatest hit. Previously
bareos-sd JobId 739: Despooling elapsed time = 00:11:16, Transfer rate = 73.96
M Bytes/second
...but now...
bareos-sd JobId 902: Despooling elapsed time = 00:48:07, Transfer rate = 14.83
M Bytes/second
This is all the same hardware with no other changes to the environment.
