We have a Bacula Server with a bonding (2 x 1GBit) Load Balanced Ethernet 
(switched LAN) running under Debian Lenny AMD64. The Storage is a Soft RAID 5 
with 5 SATA Disks.

Performance Test 1:
 dd if=/dev/zero of=test bs=1M count=1000
1048576000 Bytes (1,0 GB) kopiert, 1,93093 s, 543 MB/s
 dd if=/dev/zero of=test bs=1024k count=1000
1048576000 Bytes (1,0 GB) kopiert, 1,78247 s, 588 MB/s


The client side is a Debian Lenny AMD64 with 1GBit Ethernet and
Windows 2003 with 1GBit Ethernet.

If i put a 500MB File via FTP the throughput go's over  67MB/s:
150 Ok to send data.
226 File receive OK.
536870912 bytes sent in 7.72 secs (67877.8 kB/s)

If i run a backup of the same host with bacula, the  Transfer rate is only 
23.47 M Bytes/second

Have any one a idea?
