Add a flushDiskCache option option switchable by //version in to regression suite

    XMLWordPrintable

    Details

      Description

      Example:
      //version flushDiskCache=true
      //version flushDiskCache=false

      This is primarily for the performance suite.
      Some queries perform a lot of disk reads and fill the OS cache, giving very skewed results, depending on what other queries proceed them.
      It would be useful to flush the disk cache prior to running some tests and time the result, then run it again and time again, so that you could see the cost of the query when it actually hits disk and when it doesn't
