Brief:

Performance engineering team of British Telecom is responsible for performance tuning various subsystems in Spine program. It focuses on performance improvement, analyzing the architecture for bottlenecks and then addressing the identified design and architecture issues, environment configuration changes, etc. A series of Proof of Concepts were required to evaluate whether efficiency analysis and performance tuning will produce deliverable and quantifiable benefits which translate into either reduced costs or mitigated penalties.

Responsibilities as Senior Developer:



Responsible for design, development and implementation of the test bed to simulate the live like environment.
Identified critical business processes, analyzed design and architecture to provide optimized solution so as to maximize output and reduce bottlenecks.
Responsible for developing prototypes in Java and J2EE to prove the concept and solution for performance enhancements.
Optimized multithreading, asynchronous services, IO reading/writing, database storage using BLOBs and zipped streams, XML Parsing using XSLT and JIBX.
Undertook performance enhancement activities including multiple parser analysis, redesigning caching/storage strategies and database tuning.
Tuning Garbage Collector, Trying various GC algorithms (And settling for ParallelGC), Tuning heap size, Tuning the ratio between Eden and Old generations (The heap ratio), Tuning connection pool, Tuning HTTP thread pool size.
Achieved 20% savings on the hardware used for PDS and ETP and 22% performance improvement in ETP Database operations.
