Hi.

I've just hardware upgraded my bacula-server to a machine with 48GB ram.
I've allocated at most 35GB to a "tmpfs" as spooling
tmpfs           /z/bacula-spool tmpfs   size=35g                0       0

And performance seems to be excellent on this filesystem (2 x LTO3 attached):
jk@bacula:/z/bacula-spool$ sudo dd
if=bacula-sd.data.16716.Hal_Daily.2008-07-09_23.58.15.LTO3-0.spool
bs=64512 of=/dev/null
124007+1 records in
124007+1 records out
7999943571 bytes (8,0 GB) copied, 4,93783 s, 1,6 GB/s

But my backup de-spooling speed sucks (at best):
10-Jul 11:31 bacula-sd JobId 16716: Despooling elapsed time = 03:06:23,
Transfer rate = 715.3 K bytes/second
10-Jul 11:31 bacula-sd JobId 16716: Spooling data again ...
10-Jul 11:34 bacula-sd JobId 16716: User specified spool size reached.
10-Jul 11:34 bacula-sd JobId 16716: Writing spooled data to Volume.
Despooling 8,000,008,095 bytes ...

Note . .. in the first 4-5 incremental jobs I actually go ~80MB/s on it, so
it has just degradede over night.

Any suggestions?

Jesper
