They're probably not very representative of today's platforms as its an old P100/Linux, but still, it's interesting. In all cases, a loop on $i going between 0 and 999,999 was run, and in each iteration, one function call was made. strlen() is the standard internal strlen(), foo() is a user function that receives one argument and does nothing (empty body): before ------ strlen("foo") 1,000,000 41.03 secs foo("foo") 1,000,000 47.26 secs after ----- strlen("foo") 1,000,000 22.73 secs foo("foo") 1,000,000 40.00 secs As you can see, the time of built in functions has been almost cut in half, which brings us to about the same area as Perl. The optimizer will hopefully bring us all the way and perhaps even further, I haven't yet tested it there.
