Source Code, Tools, Developer Notes and Performance Metrics
This program is modeled after the TimeIt program provided with the Microsoft 2003 Resource Kit. The reason I wrote TimeMe is MS's TimeIt does not run on Windows7.
There are no switches or options to TimeMe, unlike the MS program TimeIt. Everything after the program name is assumed to be part of the target program to be measured.
TimeMe starts the target program suspended, then creates several Performance Counters and then resumes program execution. The target program is also run under debug trace mode so the program exit can be detected to grab the process specific counter values before the program exits.
Output of TimeMe:

The Microsoft TimeIt program has severeal command line switches and stores results in a database. My version of TimeMe appends the results to a text file 'TimeMe.log' but does not support any of the MS options.
Help banner:timeit -? Invalid switch -? Usage: TIMEIT [-f filename] [-a] [-c] [-i] [-d] [-s] [-t] [-k keyname | -r keyname] [-m mask] [commandline...] where: -f specifies the name of the database file where TIMEIT keeps a history of previous timings. Default is .\timeit.dat -k specifies the keyname to use for this timing run -r specifies the keyname to remove from the database. If keyname is followed by a comma and a number then it will remove the slowest (positive number) or fastest (negative) times for that keyname. -a specifies that timeit should display average of all timings for the specified key. -i specifies to ignore non-zero return codes from program -d specifies to show detail for average -s specifies to suppress system wide counters -t specifies to tabular output -c specifies to force a resort of the data base -m specifies the processor affinity mask
