My database saves at about 22,000,000 pages an hour.  I have taken the
messages from the log and they are consistently the same.  I do not know
what is causing this.  There were some performance problems with mirrored
databases, but I thought they were fixed at your level.

I have a strange problem that I have been working with IBM on, but was told
it's "working as designed".  I have a new TSM server, which started life as
5.1.1.6, upgraded to 5.1.5.2 at IBM's request, then just did 5.1.5.4 today
after seeing it had been released.  I back up the database, which is only
124000 pages since it is a new server.  It backs up the first 90000 pages in
a couple of minutes.  The last 34000 pages take over an hour.  While this is
happening, there is very little CPU and I/O going on.  I have tried the
database on SCSI, and on FastT700, the backup file on each, etc.  I can make
it go away temporarily if I unload and reload, but once this database gets
bigger, that will not be an option.  Any ideas?  Thanks.
