 #### How the performance is measured:
 
 Both tcl-core as well as tclclockmod has a file [tests-perf/clock.perf.tcl](./tests-perf/clock.perf.tcl) which can be used to compare the execution times of original clock and tclclockmod. It can be also simply performed from the tclsh, with and without loading of the module.<br/>
