I've written about this before, but it has come up a couple of times this week - Not all defraggers are the same.
Some are free, some cost money, some have very intelligent algorithms, some aren't so good. Tweaking and optimising a defragging algorithm takes time. Time typically has a cost associated with it.
One thing we've learnt over the last three years is that Domino places some rather unique requirements on a defragmention algorithm. The following rules seem to always apply:
the longer the server has been running, the worse state it is in.
available freespace is likely to be highly fragmented.
it is not unusual to have highly fragmented multi gigabyte database. As a rule, multi gigabyte files (30GB+) outside of Domino are fairly uncommon.
it is difficult to defrag files that are constantly changing.
In an environment where you have a lot of small databases with a lot of disk space available, the job of a defrag engine is rather easy.
As you move up the scale, and enter the real world of Domino it gets harder and harder, and the algorithm used by the defrag engine needs to be smarter.
I've been asked a number of times, why not just use the 'Free stuff'. Free defragging products typical are:
not designed from the ground-up to meet the needs I outlined above.
perform relatively simple cluster moves.
do not handle multi-gigabyte, constaintly changing files very well.
are a simple wrapper around a freeware utility that falls in one of the categories above.
I'm not saying they are bad, or don't work, but what I will say is this - developing a Domino specific defragging engine has been challenging, very time consuming and costly.
Given all this, we are please to announce the availability of Defrag.NSF version 2.06. We have done a significant amount of fine-tuning to the defragging engines for this update and we are excited about the results we're obtaining.

DBMT has a nasty little side-effect
Wed, May 29th 2013 10:28p Adam Osborne A lot of been written about the benefits of DBMT - some have even said that it alone is a reason to upgrade to Domino 9. Everybody agrees that it is a nice addition to Domino. It does however have a nasty little side-effect that comes from running the tool, and that is file fragmentation. In fact the DBMT has the ability to fragment NSF files very very quickly and severely. To check the effects we took a small test server we have and plotted fragmentation between invocations of the DBMT. Her [read] Keywords: domino

Make sure you get the most out of your Notes 9 client upgrade from the start (part 2)
Fri, Apr 12th 2013 12:52a Adam Osborne In our previous post on the subject we highlighted the fragmentation introduced during our client upgrade and how Defrag.NSF for Notes removed that fragmentation automatically when we started the Notes Client. http://ab1osborne.blogspot.com.au/2013/04/make-sure-you-get-most-out-of-your.html As a result of that post we received some questions, here are some topics/questions that people were interested in knowing more about.

Warning - There is no basic Widget support in iNotes 9
Thu, Apr 4th 2013 4:49p Adam Osborne This one caught us by surprise - the bottom line is the 8.X technique for adding a Widget to the iNotes Mail outline no longer works. It is summed up by this line in Technote 1627817 "In iNotes 9.0, the Widgets folder in the Mail outline is no longer supported. The documentation surrounding this feature remains in the iNotes 9.0 documentation but does not apply to iNotes 9.0." Go ahead, read it again ... Instead of using the old technique of a single XML file, you need to follow the proced [read] Keywords: inotes

Make sure you get the most out of your Notes 9 client upgrade right from the start
Thu, Apr 4th 2013 4:28p Adam Osborne If you're installing or just installed Notes 9 you might want to consider a Defrag to defragment any new fragmented files. Below is an example of what happened on one of our clients when we recently upgraded from Notes 8.5.3 to Notes 9. Prior to installation the Notes Program and Data directories were completely defrag via the Defrag.NSF for Notes Client which is fully automated to maintain the client's files. After the install we see the following in Defrag.NSF for Notes log file: [2013-0 [read] Keywords: lotus

Adding a World clock to iNotes for your traveling users
Thu, Feb 28th 2013 11:25a Adam Osborne Here's how to configure a handy World Clock widget for inotes. You can allow users to create their own widgets but here we are just setting a widget that will be available to all inotes users on a particular server and cannot be removed by the users. First if you haven't already done so, you would need to enable widgets in inotes by checking the following mail policy setting on the Lotus iNotes -> Configuration tab of a Mail policy settings document: Now the "Widgets" folder wil [read] Keywords: domino
