ufsdump simply does ufsdump. Amanda OTOH has to do an estimate, do the dump 
via gzip to compress it, and then write the dump to tape. If your holding 
disk is smaller than the sum of your two biggest disklist entries (I see you 
only have 2GB of holding space allocated) then you run the risk of having to 
do dumps direct to tape, which is slow particularly when using server 
compression as you are as you won't be able to keep the tape streaming. Then 
of course there's the amanda overhead i.e the time taken for amanda to do its 
things e.g. write indices etc. other than just the backup

All these factors together are what makes Amanda slower than straight ufsdump 
for this simple case. If you're using amanda in a more normal configuration 
i.e. where she's backing up numerous clients to one tape device with 
sufficient holding space allocated, then she is quite fast because she has 
multiple clients dumping to the server and then one process on the server 
keeping the tape drive going at full speed.
