Colin Butcher, FBCS, CITP, CEng, of XDelta Limited.


This session will cover the principles governing systems performance when designing and trouble-shooting systems and their associated infrastructure.

There are a wide range of issues to be considered, especially those affecting throughput, response times, scalability and availability. Performance is not something that can always be dealt with by system tuning or simply buying bigger hardware. Performance issues frequently result in systems failing in some form or other, which affects availability and causes disruption to service. Understanding the characteristics that govern performance helps us to design and implement better systems.


Colin is a consulting engineer who specialises in leading the design and implementation of mission-critical and disaster-tolerant systems. He started XDelta Limited in 1996 and works with a wide range of OpenVMS based systems and their surrounding infrastructure. Colin has been responsible for the design and implementation of systems engineering projects in a wide range of industries such as aerospace, power generation, finance, healthcare and transport.

Colin has been involved with the world-wide OpenVMS community for over 30 years and is a well-known speaker on OpenVMS related topics with specific interests in availability, performance, security, networking and storage. His background is in large scale systems engineering, including software design and development.
