Andrew is a specialist in advanced "black box" performance tuning of enterprise scale Websphere infrastructures and is quick to identify bottlenecks. There is no "one size fits all" when it comes to performance tuning, each configuration will require it's own unique set of tuning parameters. And remember ... performance tuning is a reiterative process that requires constant revisiting to achieve optimum performance and throughput. End to end performance testing is one of Andrew's specialist skills ... all components in the solution will come under his scrutiny and be optimally tuned. In instances where a bottleneck occurs in infrastructure that is not under Andrew's control then he will liaise with the relevant resource(s) to ensure that optimum tuning parameters are applied.
The integrated WebSphere Performance Monitoring Infrastructure (PMI) and Tivoli Performance Viewer are useful tools to get an idea of what a system is doing. However, these tools are cumbersome to use, making it difficult to drill down to the root cause of system performance bottlenecks. Andrew uses custom built tooling that has low system overheads, fast refresh rates and is designed to drill down to the root cause rapidly. Andrew has a no fix, no pay policy when it comes to performance tuning so why not try him out today, you have nothing to lose!
