Hi,
the TCPWINDOWSIZE is interesting to adjust if you have so called 'lfp ... long
fat pipes' , that means
much data over a long distance network, something like WAN and not on a LAN -
afaik
You may check the manual about tspwindowsize.
Goran, I think you have missed something: beside the 'elapsed processing '
and 'objects compressed' you should give the other values , whats happened
Its not clear how many files really are backed-up - or do you want to backup
every time all the files
--selective or incremental backup ?
Are both Client and server connected on the same LAn and what Network
Interfaces do they have ?
Another question maybe : how many Filesystems does the Client have - all files
in one ?
Greetings
