Perfomance analysis

Java Profiler

We have developed a Java performance analyzer tool that allowed us to spot a few hard-to-tell issue at our clients. We have decided to make it open source (OKTECH-Profiler) and accessible for everyone. Key features:
  • low-overhead profiling (applicable in production environments)
  • uses stack trace sampling and/or byte-code instrumentation
  • is able to work remotely, behind unreachable firewalls, no direct supervision client is required

For example we can use highly-optimized local storage to work the same way SimpleDB would work, allowing us to execute local unit tests, prototyping and debugging really fast.
