[Dump-users] dump performance

[Eros A. <er...@la...>]

I am using dump to write to a remote tape and I am surprise of the low transfer
rate I have.
I am wondering if I am right and if this is cause by the program itself.
What, if any, steps can be taken to improve?  

I have dump-0.4b14-1 on a RH 6.1 x86 w/ide disks.
The remore tape is a SCSI-2 UltraWide Sony SDT-10000 ( transfer rate
non-compressed 2.4 MB/s) attached to a Alpha XP1000 workstation.
Both machine have fast ethernet connected to a 3Com switch.

Here is what I got:
  DUMP: DUMP: 2569003 tape blocks on 1 volumes(s)
  DUMP: finished in 3595 seconds, throughput 714 KBytes/sec
  DUMP: Volume 1 completed at: Sun Feb 13 00:43:07 2000
  DUMP: Volume 1 took 1:00:00
  DUMP: Volume 1 transfer rate: 713 KB/s

Yhanks for any hints.
