The Domino Database Optimizer. Our new product is on its way - Preliminary testing on SSD

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

and the story is another example of millions of fragments leading to crap performance.

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
Thu, Nov 26th 2015 11:58p   Adam Osborne
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
