The Domino Database Optimizer. Our new product is on its way - Preliminary testing on SSD|
Sun, May 15th 2016 11:19p Adam Osborne
Our new product is undergoing preliminary testing in our lab and is showing some great performance gains even with Domino attached to the latest SSD storage technology. We are using lightning-fast SSD storage here and seeing these results. It's further proof that even though a super-fast storage/back end will help it is not a complete performance solution and in fact true optimal performance results from acknowledging and tuning each individual component of a system. To not apply that basic pr

Here are some slides from Connect that talk about Notes and Domino plans. Naturally anything could change.

You can see it and measure it - the savings are real|

The following graph shows how split I/Os are basically eliminated during a backup of a defragged file. It also shows the overall massive reduction in backup times. and yes it happens on a SAN (I welcome any proof to the contrary).
SANs - They aren't magic|

Wes Morgan from IBM summed it up perfectly in his "Wrestling The Snake - Performance Tuning 101" Lotusphere Presentation from 2012. Last week one of our customer's asked if we could suspend overnight processing in The Preemptive Email Vault because their SAN was overloaded. On inspection of the issue we could see that over 50% of the I/O was due to file fragmentation. Luckily the answer is simple.
Big savings on backup times|

Sometimes the best way to see the benefits of a change is to visualize it. Below is a chart showing the difference in backup times of a large mail file before and after it has been defragged. Look at the disk queue length and the overall backup duration. There is a significant difference. For a solution to this problem check out Defrag.NSF

The clean up continues... found an old OS/2 Warp 4 disk. IBM did amazing things on very limited hardware. and Word Pro loads in like 0.002 seconds Hard to believe they did all this and zero came from it.

Reading a recent article from Brian Morin of Condusiv Technologies, we noted a couple of great points we can relate to: "Typically, as soon as we mention "fragmentation" and "SAN" in the same sentence, an 800 pound gorilla walks into the room and we’re met with some resistance as there is an assumption that RAID controllers and technologies within the SAN mitigate the problem of fragmentation at the physical layer...... As much as SAN technologies do a good job of managing blocks at the
I wonder if IBM will update DAOS now SHA-1 has had a collission ?|
Thu, Oct 15th 2015 10:44p Adam Osborne
I can imagine a scenario where you could give Domino a SHA1 generated file and it'll give you the real file... could be a problem.. could be a huge problem. https://sites.google.com/site/itstheshappening/
It’s just NOT ok to treat on-premises customers as second class citizens.|
Mon, Oct 12th 2015 9:40p Adam Osborne
Lots of vendors are doing it. They use maintenance subscriptions to pay for the development of the cloud solution. Meanwhile the poor old on-premises customer sits back and hopes that something trickles down from the cloud that is useful. It’s like putting gas in someone else’s car. A free ride while ever you can get away with it. Time to ask for a discount. Cloud first is fine, just make sure cloud subscriptions pay for it.
Domino Fragmentation Analyser - FAQ|
Fri, Sep 4th 2015 2:01a Adam Osborne
What is the Domino Fragmentation Analyzer (DFA) ? A new Free and easy to use tool that runs in a Command Prompt and will quickly analyse Domino and produce a comprehensive report of fragmented nsf files. The DFA concentrates only on analyzing nsf files and will highlight the total number of nsf files fragmented, how many fragments each of those files are in, the most fragmented nsf file and also freespace info for the drive hosting the Domino Data directory, including freespace fragments and the
Domino Fragmentation Analyzer's first major find - 13,954,029 Fragments on a single server|
Wed, Sep 2nd 2015 9:29p Adam Osborne
We just got the following report in from a server (9.0.1 FP 3) with 2000 users on it. Lots of data, and long backup times. It's a mess, with nearly 14 million fragments (one NSF file has over 173 thousand). The good news is, here we have an opportunity to improve performance in a huge way! They didn't know... and now they do.. check to see what DFA might be able to tell you!

SANs and VMs still need help|
Tue, Jun 16th 2015 2:18a Adam Osborne
Don't ignore fragmentation on your VMs and SANs, things still get very messy and at the end of the day the poor old operating system knows no better and it all slows down. Let Defrag.NSF rescue your Domino Server and Backups from I/O bankruptcy. Here is example of one site that recently took back control.
