[Click] Profiling the performance of an element.

[Beyers Cronje]

One way would be to use:

CycleCountAccum
<http://www.read.cs.ucla.edu/click/elements/cyclecountaccum> collects
differences in cycle counters
PerfCountAccum<http://www.read.cs.ucla.edu/click/elements/perfcountaccum>
collects
differences in Pentium Pro performance metrics
PerfCountInfo<http://www.read.cs.ucla.edu/click/elements/perfcountinfo>
turn
on Pentium Pro performance metrics
RoundTripCycleCount<http://www.read.cs.ucla.edu/click/elements/roundtripcyclecount>
measures
round trip cycles on a push or pull path
SetCycleCount<http://www.read.cs.ucla.edu/click/elements/setcyclecount>
stores
cycle count in annotation
SetPerfCount<http://www.read.cs.ucla.edu/click/elements/setperfcount>
stores
Pentium Pro performance metric in annotation
See http://www.read.cs.ucla.edu/click/elements#counters

These are only available in the linuxmodule package.
