For C and Rust and less for the next few, the testing set is too small to be significant. Process management and system load have way more effect of these than on the others. If I however make the test-set bigger, the slower processes would take too much time.
I already tried to subtract startup-time, but as the startup-time is about the same as the runtime, and so low that noise has more impact than the actual run-time, it is more like an indication that these processes are significant faster than the rest.
Also note that the goal of these graphs are to show relative speed between the perl methods available. I added the other languages later out of curiosity.
Enjoy, Have FUN! H.Merijn
