IBM Notes/Domino V10 will be released IBM Domino V10 World Premiere in Frankfurt / Germany. If you‘re not on at least 9.0.1 yet 9.0.1 FP10 IF4 is a significant improvement Again, IBM Notes V10 arrives ODS of local databases ODS = On Disk Structure. ODS 16 = Notes 2. ODS 17 = Notes 3.

We use notes 9.0.1 and 8.5.3. In our database properties I see that we have ODS version 41.. Does this need to be upgraded? I read some articles that this IMPROVES performance of the database.
Can anyone please tell if this statement is true?

The statement is true. Go ahead and upgrade to the latest ODS.
From the IBM documentation on the 9.0.1 release:
'In this release, Domino supports file format, on-disk structure (ODS) 51.'
'The current level of ODS provides potential improvement for I/O, folder optimization, compression, and attachment consolidation.'

ODS 41 is the Notes 5 on-disk storage format. Notes 5 was released 18 years ago, in 1999. IBM engineers have had all that time to come up with ways of optimizing the format in order to improve the efficiency of the storage and retrieval algorithms. Furthermore, there have been major improvements in the typical configurations and capabilities of server hardware - with much more memory and faster CPUs available - allowing IBM's engineers to design algorithms that take advantage of resources that were never available in the 1990s and optimize the ODS for those algorithms.
The performance of most applications in most Notes/Domino environments is i/o-bound, so of course using the latest ODS on modern hardware and gaining the benefit of 18 years worth of optimizations made to the software can improve application performance. Whether your applications are i/o-bound in your environment and will benefit from the improved performance characteristics of ODS 51, however, is a question that only you can answer definitively.
