Hi, We have Solaris 10 Servers, 3x Sun V240, one of them is the backup-server with the storage deamon and director the others are backed up to the tape at the backup-server.
The backup-server has a 1.3GHz CPU and 1Gb RAM, U320 SCSI-Kontroller (on board) and a second U320 controller with the Tandberg SDLT320 tapedrive. Networkspeed is at 1Gbit. We alos testet some transfers with "Pipe Magic Tools" and get more then 30Mb/s in the average. The disks I testet with bonnie++ and the write/reed is more then 30Mb/s. We compiled bacula to work with postgre-sql. All your tips did'nt change anything, I have only a throuput of arround 300-350Kb/s. I also added the spooling-parameter. With spooling it takes arround 10-20min to spool data and write them down to tape at 2MB/s. But the save of the attributes (writing to the catalog) needs 2h or more! I tried many combinations and recompiled bacula also with Postgres 8.1, Postgres 8.0, with CFLAGS=-O2/CXXFLAGS=-O2.... I compiled it with gcc 3.4.4, which I compiled myself, because on solaris 10 there is'nt any binary distribution. I think that there are 2 Problems, one is the performance of Bacula or Postgres itself and also some problems with the tape. I did'nt get more then 2.6Mb/s with the ufsdump from solaris.
