More on the same story .. Im getting there :)
Seems that the bottleneck indeed was the gzip process ..
I've changed my disklist/amanda.conf to no longer compress the images, and
instead rely on the hardware compression in the LTO drive
(trading tape space for speed ;) ), and the results are rather dramatic.
A normal amanda session with compression takes between 10 and 15 hours,
running whitout compression finished in 3.5 hours .
I still noticed that the dumper process is the bottleneck, but dumper now
gets a performance of about 3 - 4 Kbps (iso sometimes down to 250bps).
Kind regards,
