Feedback from Consulting Customers

Bostjan Gspan, Senior Technical Account Manager, Microsoft Slovenia

“Ramesh worked for my customers several times. In his training capacity the best feedback I got about Ramesh's work was from the most demanding and already knowledgeable people.

On another occasion Ramesh was tuning performance of an already optimized SAP on SQL system at my customer. He pinpointed the best candidate queries for optimization and successfully optimized them beyond all customer's expectations.”

“Ramesh is a fantastic database consultant. We needed someone with deep MS-SQL Server knowledge to help identify and correct some major performance issues for our largest customers. Within a short period of time he was able to diagnose our database problems, help our customers get back on track, make salient recommendations for future hardware planning all within budget and time constraints. Ramesh is very easy to work with and listens to what his client’s needs are. It was great to work with him and I would highly recommend him to anyone who needs a MS-SQL Server expert.”


John Ness, System Manager, Bühler AG, Switzerland

"The report presented by Ramesh is - as all his work tends to be - short , concise and to the point. Ramesh has pinpointed issues that are hidden from the normal 'SAP administration' eye and - not surprisingly - found coding issues in the 'application'.

Having previously visited a 'SQL Server Performance Tuning and Optimization' course at Microsoft (Switzerland) I was already accustomed to the straight-forward approach that Ramesh tends to take. However, he will always take time to explain SQL internals and is willing to spread his knowledge.

I highly appreciate Ramesh from a professional perspective and would recommend his courses and his consulting work to anybody running an SQL 200x Server and encountering performance issues. It was a pleasure having Ramesh here at Bühler AG in Uzwil.

I am already looking forward to visiting his next course at Microsoft in Zurich, Switzerland.”

Dipl.-Ing. Friedrich Kastner, IT System Manager, Energie AG, Austria

“Ramesh hat im Rahmen eines Migrationsprojektes Performance-untersuchungen bei uns, zunächst remote, dann direkt bei uns durchgeführt.

Mit verschiedenen Tools wurden Messungen hinsichtlich mehrerer Komponenten (Datenbank, Server, Netzwerk, Storage) durchgeführt. Wir bekamen dadurch ein besseres Bild über unsere Performanceengpässe. Ramesh hat im Rahmen der Untersuchung auch seine weltweiten Kontakte zu Spezialisten genützt um Unklarheiten beseitigen zu können bzw. weitere Information einzuholen.

Zuletzt hat uns Ramesh einen Bericht mit den Ergebnissen und Verbesserungsvorschlägen zukommen lassen.

Wir bedanken uns für die gute Zusammenarbeit und die Unterstützung.”

[“Within the scope of a migration project Ramesh has carried out performance investigations, at first remotely, then directly with us.

With different tools measurements were carried out concerning several components (data bank, server, network, storage). We thereby got a better picture about our performance bottlenecks. Ramesh, within the scope of the Investigation, has also used  his worldwide contacts with specialists in order to remove lacks of clarity or to catch up further information.

Lastly, Ramesh sent us a report with results and recommendations for improvement.

We are thankful for the good collaboration and support.”]


Tatjana Petrovic, Technical Support Center, Kapsch Telematic Services GmbH, Austria

“I have met Ramesh at the SQL Server Performance Tuning Workshop in 2008. Impressed by his vast knowledge I approached him with the request to assist us at a project we were doing in Czech Republic at that time. Since Ramesh swiftly and efficiently solved our SQL Server Performance Tuning problems we decided to engage him on a regular basis.

We at Kapsch are now looking back at a history of 5 years, working on multiple, international projects and we are VERY SATISFIED with Ramesh’s service. Ramesh is a dependable and most valuable help whenever SQL Server Performance Tuning problems occur. He has always solved our known performance issues and, additionally, identified scenarios which might become an issue in the future and tackled them in a preventive way.

We are very happy that we will continue our co-operation also in the future as two new, work intense projects are coming up. I can warmly recommend Ramesh to anyone who is in need of SQL Server Performance Tuning expert advice.”


Thomas Frank, Software Development, Liebherr GmbH, Austria

“Die Zusammenarbeit im Projekt war sehr konstruktiv und angenehm. Die Herangehensweise und schlussendlich die Identifizierung von Verbesserungsvorschlägen hat mich sehr beeindruckt. Die besprochenen Vorschläge werden momentan geprüft bzw. wurden zum Teil schon umgesetzt. Vielen Dank!”

[“The cooperation in the project was very constructive and enjoyable. The approach and finally the identification of improvement proposals has really impressed me. The proposals are currently being tested and/ or partly implemented already. Thank you!”]


Trevor Brown, Network Administrator, SymMetric Revenue Services Inc., U.S.A.

“Thank you very much!  I just got done going through your report for the first time and I must say, I’m very impressed with your work! We can definitely implement some of the changes without issue, however, some of the queries we are not able to modify.  This is not an in-house application (except for the Sp. database), it’s an Imaging and workflow management package from Oracle.  We’ll need to go through this thoroughly on our side and discuss the changes suggested to see what can & can’t be done. I’ll get back to you as soon as we have the opportunity to get through all the info you’ve provided. Thanks again for your assistance!”


Troels Eriksen, Operations Architect, NNIT A/S, Denmark

“Seeing you work on a real production system / problem was very impressive – structured approach and using the very same scripts and tools that you showed during the course. Very nice!”


Bernhard Fiedler, Team Leader Development, Beta Systems Software AG, Germany

“Herr Meyyappan hat uns sehr schnell und unkompliziert bei der Analyse eines Locking Problems unserer Datenbank Anwendung helfen können. Beeindruckend war, wie schnell Herr Meyyappan die Situation analysiert hat und damit auch sehr effizient eine Lösung finden konnte.”

[“Mr. Meyyappan swiftly and easily helped us in the analysis of a locking problem in our database. It was impressive how quickly Mr. Meyyappan analyzed the situation and thus could find a very efficient solution.”]


Alexander Holy, Head of IT department, derStandard, Austria

“ is one of Austria’s most frequented web sites. Interactivity and personalization create a lot of stress and activity in our SQL Server database.

A day of database performance analysis and tuning with Ramesh Meyyappan helped us to identify and resolve our worst performing queries and provided us with all the necessary information to continue on our own. I’m wholeheartedly recommending Ramesh’s on-site consulting services to anyone who has exhausted all conventional database tuning and optimization. Since we were able to speed up critical portions of our application, we could noticeable speed up things with only a single day of consulting work.”


Egil Pedersen, Developer, Det Norske Veritas GL AS, Norway

“Thanks for the workshop. I found it very useful as the topic that you presented on Thursday was directly relevant to my everyday work as a developer. The level of detail was excellent, and issues concerning the handling of execution plans relating to stored procedures was especially useful. The accuracy of your findings was very good and I look forward to reading your report as well.”


Stein Ove Rov, IT Manager, Komplett AS, Norway

“I want to thank you for doing a excellent job for us. The report we got from you gave us a lot of valuable information. You have helped us a lot with the job you did for us. In my opinion, this is one of the best SQL engagements I have ever seen.

As I said, you have done an excellent job for us, Thanks a lot !!”


Oliver Vettel, Managing Director, Indivis GmbH, Germany, after a project delivered for Hoffmann-La Roche, Germany

“Ramesh, as always, this was exceptionally helpful.

The level of SQL Server knowledge and the commitment to resolving our issues are outstanding.”


Patrick Hable, Managing Director, 2iQ Research GmbH, Germany
