    Description

      After applying the patch for LU-1397, Fujitsu has seen performance for their benchmark suite decrease by about 7%. This is pushing the system outside of the acceptance range, and so therefore a high priority for us. I am trying to get information about what exactly is going more slowly (what application/file operations), but would it be possible for someone to review the patch to see if there are any areas that could be improved?

      Thanks.
