Introducing Myself
Hi all!
My name is Shlomi and I subscribed to this list because I currently maintain
https://github.com/thewml/website-meta-language (WML) which is used by the
Debian site and which https://github.com/xtaran , who is a debian dev, has given
me some input on.
Now, I've done a lot of work on refactoring and optimising the wml source, so
it won't serve as an example for bad code (see
https://perl-begin.org/tutorials/bad-elements/ ) and also so my wml-based sites
will build faster. I extracted a perl5 API that eliminates some fork()+execve()
and which improved performance for my sites and was adapted to the debian site
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900749 . Current timings
are:
Before (make -j4):
5150.42user 722.23system 29:46.58elapsed 328%CPU (0avgtext+0avgdata
607256maxresident)k 510336inputs+1485768outputs
(477major+170659478minor)pagefaults 0swaps
After:
3390.15user 558.96system 26:09.35elapsed 251%CPU (0avgtext+0avgdata
607368maxresident)k 420840inputs+1485168outputs
(661major+126278869minor)pagefaults 0swaps
I'm not using -j4 for the new version but it uses
https://metacpan.org/release/Parallel-ForkManager-Segmented
----
Anyway, I also spent some time converting the sources of
https://github.com/shlomif/perl-begin from wml to
https://metacpan.org/pod/Template and while it was quite a lot of work, it made
the brute rebuild time of the site over two times faster (and there is some
overhead). So I can recommend to gradually convert debian-www away from wml as
well for optimising the build time.
Regards and happy holidays,
Shlomi
