[Dirvish] performance issues with dirvish

Hi folks,
I'm using dirvish for a few weeks now and have some questions regarding
its performance.
During the last weeks I've been performing backups of several partitions
of my harddisk, but somehow the most critical "fails": my root partition.
The first backups took less than an hour, so I tried rather often
running the weekly¹ backup of my root partition manually. Actually, I
allowed dirvish to run for more than 24 hours on Tuesday. Turned out,
that there were some NFS errors (yeah, I'm copying files over to a NFS
share). So I took care of them and started dirvish again today.
After two hours of running, dirvish still wasn't finished - should I be
more patient? Also I found out, that after killing dirvish there were
*two* rsync-processes left running...apart from the fact that dirvish
should maybe tell rsync to quit, when killed (I sent a TERM) - why are
there two rsyncs doing the same (at least it appears so to me):

> root      9350  0.2  0.1  14752  1820 tty2     D    19:06   0:26 rsync
-vrltH --delete -pgo --stats -D --numeric-ids -x
--exclude-from=/media/nas/backup/current/terra/20090217-1906/exclude
--link-dest=/media/nas/backup/current/terra/20090124-1548/tree /
/media/nas/backup/current/terra/20090217-1906/tree
> root      9351  0.3  0.3  58484  3108 tty2     S    19:06   0:42 rsync
-vrltH --delete -pgo --stats -D --numeric-ids -x
--exclude-from=/media/nas/backup/current/terra/20090217-1906/exclude
--link-dest=/media/nas/backup/current/terra/20090124-1548/tree /
/media/nas/backup/current/terra/20090217-1906/tree

Kind regards and thank you for your time,
Frederik Braun

1) concerning the weekly backups, I thought about switching to daily or
hourly backups...how often do you run dirvish?

P.S.: You got some love from German computer magazine c't
(http://www.heise.de/ct , issue 22/2008) that's how I got to know dirvish ;)
