  • tried to set up the VM server in office… too slow!
  • trouble-shooting slow query
    • copying to tmp table is the bottle neck
    • tmp_table_size is set to 16M = max_heap_table_size
    • -- set the temp memory size to 512MB
      SET tmp_table_size = 512000;
    • slightely faster on mine…
