Benchmark is generally used to time/compare either subroutines or strings of code that can be eval'd rather than whole external scripts.

That said, you might get away with using "`scriptname var var`" or q[system "scriptname var var"]. Ie. Invoke the scripts using backtickes or system.

This would mean that you would be timing not just the run-time of the scripts, but also the load and compilation time plus the time taken to fork a process, find and load the shell (could be avoided) and the perl executable, which may or may not be useful for your purpose. There are also other possible caveats of doing it this way.

If you want to time a complete script from start to finish like this, many OS's have a simple shell command for doing so. Native CMD doesn't, but depending on how accurate you need the timing to be, you can get close by setting the prompt to include the current time ($T) and then do the math yourself. There are also several freeware tools around that can do this.

Examine what is said, not who speaks.
1) When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2) The only way of discovering the limits of the possible is to venture a little way past them into the impossible
3) Any sufficiently advanced technology is indistinguishable from magic.
