Hotspots View

The Hotspots view displays a list of all instruction calls that lie above the threshold defined in the XSLT/XQuery profiler settings.

By opening a hotspot instruction entry, the tree of back-traces leading to that instruction call are calculated and shown.

Every hotspot is described by the values from the following columns:

• Instruction - The name of the instruction.
• Percentage - The percentage number for this hotspot entry with respect to the total time.
• Time - The inherent time in milliseconds or microseconds of how much time has been spent in the hotspot, along with a bar whose length is proportional to this value. All calls into this instruction are summed up regardless of the particular call sequence.
• HitsCalls - The invocation count of the hotspot entry.

If you click the handle on the left side of a hotspot, a tree of back-traces will be shown.

Every entry in the backtrace tree has textual information attached to it that depends on the XSLT/XQuery profiler settings:

• A percentage number that is calculated with respect to either the total time or the called instruction.
• A time measured in milliseconds or microseconds of how much time has been contributed to the parent hotspot on this call-path.
• An invocation count that shows how often the hotspot has been invoked on this call-path.
  Note:

  This is not the number of invocations of this instruction.
• An instruction name that also contains its attributes.
