Experience summary
2012-15: Quango Computing - Principal software developer, cloud-capable performance testing tool; 5 years
I am currently the principal (and sole) developer on a project to produce a cloud-capable, and very high throughput, performance testing tool based on JMeter. This extends a distributed, JMeter-based, performance testing backend that I developed earlier. The extensions include an RMI-based Java client that is performance testing process aware and a J2E server. The tool supports multiple cloud providers both public and private. I anticipate a new level of simpliclity and a new price point for large scale performance testing. Currently the tool can test at 165,000 tps sustained for one hour with higher performance well in sight. The work has R&D status from the Australian government for tax purposes.
