Zoltan - With over 8 million files, getting the file list from the
         server before backup data transfer is obviously a big factor.
Incrbydate will help somewhat, and is worth trying one night.
The client system may have 2 GB of real memory, but much of that may
already be tied up, as I'd expect it to be busy as a mail server.
AIX monitoring would show that.

If you haven't already, review "Backup performance" in
http://people.bu.edu/rbs/ADSM.QuickFacts to have a look at that
variety of factors, including TSM server db caching, as it may be
taking too long to provide the file list to the client.
Look also for any indications of I/O contention or retries on the
server disk due to soft I/O errors, which will slow retrieval.
