Fw: Domino 8 compression

Let's see if I get an answer on the midrange l list...

I have several domino servers on this one lpar. One of the Domino servers
is saved with it's own save. (It's quite significant.)

I did two changes:
1 - Used some nice Domino 8.0 (not the 8.5 DAOS stuff yet) compression
that freed up 200GB or just under three 70gb disk drives.
2 - Deleted 850 Domino archive log files and turned off archive logging.
These 850 files really didn't take up an appreciable amount of space.

The length of the save duration didn't really change that much. Summary,
only chopped off 5 minutes by using three less of our 70GB disk drives.
What's the deal, it's the number of the files and not the size? So did we

save the 5 minutes by removing the 800+ insignificant l_ archive log
files and not by the compression of the large files which freed up over
200GB?

Before compression:
05/11/09 17:32:13 start
05/11/09 19:01:48 2017181 blocks processed for sequence 1, volume AMON15
05/11/09 20:33:31 2042477 blocks processed for sequence 1, volume AMON25
05/11/09 21:00:36 576892 blocks processed for sequence 1, volume AMON35
05/11/09 21:00:40 4308 objects saved.

After compression:
05/18/09 17:32:12 start
05/18/09 19:01:48 1742161 blocks processed for sequence 1, volume AMON11
05/18/09 20:33:45 1747936 blocks processed for sequence 1, volume AMON21
05/18/09 20:55:23 387384 blocks processed for sequence 1, volume AMON31
05/18/09 20:55:26 3555 objects were saved on volumes AMON11 AMON21 AMON31

I figure the number of blocks stored on each tape decreased because the
data is now compressed and tape compression could not compress it down
much further.
