"Also worth mentioning is what didn't change this year: multi-core support and increasing concurrency is still where the hot action is; profiling concurrency issues is still the most challenging area of performance; and the performance issues that you encounter are just the same as they have been for years - and they are, in order of decreasing frequency encountered: database access; memory leaks; distributed applications; concurrency; garbage collection."
