I am Shanti Subramanyam, a software engineer interested in all things performance. My current focus is web performance but in the past I have worked on performance of server applications and infrastructure, with special emphasis on workload/benchmark design and construction. This blog is about performance and scalability testing, workloads and tools, open source technologies and anything else that I find interesting. I currently work at Yahoo! on improving the user experience. As I worked on open source web2.0 technologies for the last several years at Sun Microsystems, I have articles based on insights gained from that experience.
