Having used both JProfiler and Yourkit recently I find that yourkit is far superior for memory problem analysis and strongly prefer jprofiler for performance analysis. Yourkit's memory analysis seems to be much easier and intuitive. For performance analysis on yourkit I have been unsuccessful in resolving any performance issue I have tried to resolve with yourkit. JProfiler shows more accurate and concise information for performance analysis with the exact number of method invocations and percent time spent in each method. I have yet to find this in yourkit. It seems yourkit just gives sampling information which is not accurate unless you are measuring thousands of invocations.
