Hi, Im a Java dev with 19 years of experience; I will use a profiler & jmeter to eliminate bottlenecks in java, tune indexes in db, make partitions based on amount of data. Only I require: 1) Sandbox env & credentials to tune sql 2) Source Code 3) A brief explain to me about core business flows, how much tx must to support, how many concurrent sessions, the error rate required in stress tests & with this I will improve performance.
