Benchmarking 10.4 for optimizer trace

    XMLWordPrintable

Details

    Description

      We need to benchmark how much slowdown we experience when we add the optimizer trace to the
      server.

      We would need the comparision for:
      1) server without the optimizer trace (current 10.4)
      2) server with optimizer trace disabled here. (currently in branch 10.4-mdev6111)

      The optimizer trace is currently disabled by default.
      Please run sysbench.
