Welcome to the web site of Julian Dyke.

I am an independent database consultant specialising in Oracle performance tuning and high availability including RAC and Data Guard. I am based in England and generally work for clients in the UK and Europe. I work for a number of customers, specialising in short term assignments from one day to around two months and consequently I am usually available at short notice.

I am a regular presenter at conferences and seminars in the UK, Europe and USA. A number of my recent presentations can be downloaded from this site.

I can be contacted either by e-mail info@juliandyke.com or by telephone +44 (0)7917 360777

CPU Performance Tests

I have a very simple CPU performance test which I run as a sanity check on every system that I work with.

In response to overwhelming demand, I have published the results which can be found here.

Thanks to all my friends who have contributed results.


I welcome any feedback about the content of this site.
