Release Test Performance Tool Kit

  • Developed and used the kit to find and analyze regression in code path of Oracle DB using TPCC benchmark for Linux.X64, Windows.X64 and Solaris.X64 platforms.
  • Added multi-threaded test cases to analyze performance at CPU saturation.
  • Kept track of regression - CPU usage (User and Kernel), Memory measurement etc. on daily labels.
  • Used performance measurement tools - Oprofile, Vtune to obtain statistics - call graph, instruction retired, branch bispredictions etc. - to find bottlenecks.
  • Profiling. Performance issues related to build process. Fine tuning of the binary post build process.
