[rdiff-backup-users] Extremely slow performance problem

[Craig Findlay]

I have a problem with version 1.3.1 backing up from a Windows server to
a Linux box. 

Following is the output from a test backup script. Both ends are at
1.3.1, the Windows server is running the native Windows version, not a
cygwin version.

Note the Elapsed time of 1 hour 54 minutes. This is an extremely long
time it seems to me to do the job, since the source is only 2292 files
and 2.2 GB in size. This test represents only one directory tree out of
40 or 50 on the Windows server. At that rate it will take days to a
single backup run on the server :(

Any thoughts why it is so slow? What testing can I do to narrow down the
cause of the problem?

Cheers,
Craig
