Just upgraded to

rakudo-pkg-Fedora28-2018.06-01.x86_64.rpm

Just as slow starting.

Are you using a 32 bit version of perl6?

If so it has no Just in Time (JIT) compiler and will be very much slower.

If you're writing a runnable script in Perl 6, I would recommend to
*always* use a MAIN sub[1]. If you're using that, you can easily
achieve the precompilation as well, with 1 line of code less.

You'd have your code in lib/Your/Program/Main.pm6:

sub MAIN (
# You can let Perl 6 handle arguments here
) is export {
# Program code here
}

Next, the script that you actually run would be in bin/program, and
contain the following code:

use lib "./";
use Your::Program::Main;

This should give you all of the Perl 6 MAIN goodness, and a faster
program.

Re: start up delay?

[Simon Proctor]

So Perl6 is a lot like Python in that modules get compiled to byte code
making them a lot faster to parse the second time around.

If you're running a 6000 line script then a lot of time is going to be
spent parsing your script every time you run it. If you instead take all
your script code and pop it into a module and have a script along the lines
of :

use lib "./";
use System;

System::start();

(Where your module code is called System.pm6 and start is the entry point
subroutine).

I think you'd find this improves the speed of the script significantly.

The program is 6160 line long plus a bunch of imported
modules.

The Perl 5 version of this program that starts three
times faster is 6354 lines long plus a bunch if imported
modules.

The slow start is not a reason to go back to p5 for
any reason.  It would just be nice if it started faster.

Sorry I wrote my earlier email on my phone without a computer to hand.
Here's a quick rundown on what I'm talking about.

--stagestats gives you the breakdown on how much time is spent doing
various steps (note that using time instead of date; date gives you a
better timing of how long something took.

time perl6 --stagestats -e ""
Stage start  :   0.000
Stage parse  :   0.089
Stage syntaxcheck:   0.000
Stage ast:   0.000
Stage optimize   :   0.001
Stage mast   :   0.004
Stage mbc:   0.000
Stage moar   :   0.000

real0m0.144s
user0m0.155s
sys0m0.032s

And generally that's going to be the case for most short programs, in these
cases especially moving to having the core of your code in modules with
give you a speed boost.

Sorry if my comments earlier were unhelpful.

Seven seconds?  Seven?  That seems *very* long indeed.

How long does it take to do:

perl6 -e ‘’

?  That should be in the order of 130 msecs.  If that’s the case,
then you’re probably doing a lot of grammar changes to Perl 6.  But
without the actual code, this remains guessing.

Not sure  :-)

On thing is if you are running large script files it came take a while. 
Moving your code into modules, which get precompiled can give a 
significant speed boost.

Seven seconds?  Seven?  That seems *very* long indeed.

How long does it take to do:

perl6 -e ‘’


$ date; p6 ''; date
Mon Aug  6 00:51:10 PDT 2018
Mon Aug  6 00:51:10 PDT 2018

$ date; p6 'say "Why is this taking so long"'; date
Mon Aug  6 00:52:17 PDT 2018
Why is this taking so long
Mon Aug  6 00:52:17 PDT 2018



?  That should be in the order of 130 msecs.  If that’s the case, then you’re 
probably doing a lot of grammar changes to Perl 6.  But without the actual 
code, this remains guessing.


What is a "gammer change" and how do I minimize them?



Any workaround for this, or is this just growing pains for Perl 6?


Not sure  :-)

Hi All,

Is it just me or does Perl 6 take about three times as long to
start up as Perl 5?  I do have a very fast machine and it takes
about seven see for some of my Perl 6 stuff to get past the
ruminating phase and start running.

Any workaround for this, or is this just growing pains for Perl 6?

Many thanks,
-T

The 'zef' program does that to great effect
