Top Java Performance Mistakes

Top Java Performance Mistakes (Andreas Grabner): Have you ever wondered why your e-Banking system is down yet again for maintenance or what problem it was that caused your check-out to take forever until it terminatqed with a weird error message? Misconfigured O/R Mappers causing millions of SQL Queries and "leaking" DB connection leaks, excessive logging that consumes all Disk I/O, memory leaks that bring the JVM to crash every couple of hours or a forgotten XML configuration entry that causes millions of "Control-Flow Exceptions" that never make it to any log file. These are some of the problems that crashed large enterprise applications in the last 12 years (some even made it to national & international news). In this session we learn how to avoid these top problems by automatically looking at key performance a architectural metrics along your continuous deployment pipeline.
