perl6-bench 做 perl6 性能分析对比

作者:袖梨 2022-06-25

perl6-bench 项目地址见:https://github.com/japhb/perl6-bench。

项目的主程序 bench 本身是用 Perl6 写的。所以运行前,得先安装好 Rakudo Star:

wget http://rakudo.org/downloads/star/rakudo-star-2014.09.tar.gz
tar zxvf rakudo-star-2014.09.tar.gz
cd rakudo-star-2014.09
perl Configure.pl --backend=moar --gen-moar
编译完成后,会在 rakudo-star 目录下创建一个 install 子目录,里面有 bin,lib 等编译完成的文件,把这个 bin 加入到你的 $PATH 里去。

sed -i 's!(PATH=.*)$!1:~/download/rakudo-star-2014.09/install/bin!' ~/.bash_profile
source ~/.bash_profile
项目的测试程序 timeall 是用 Perl5 写的。运行前,也得安装几个 CPAN 模块:

cpanm Capture::Tiny Data::Alias DateTime JSON JSON::XS List::MoreUtils
然后就可以开始测试了:

./bench setup
这个命令会在 components 子目录下逐一 clone 下来各种可以测试的 perl6 实现的源代码 git 库,包括有:

arane   niecza  nqp-jvm   nqp-parrot  perl5    rakudo-jvm   rakudo-parrot
moarvm  nqp-js  nqp-moar  parrot      perlito  rakudo-moar
下面就开始正式测试了。用时同样会比较长,和上面 git clone 一样,都建议放在 screen 里运行。

然后设定本次测试你打算对比哪些:

export CHECKOUTS='perl5/v5.20.1 rakudo-jvm/2014.10 rakudo-moar/2014.10 rakudo-moar/2014.09'
这个写法规范是:git 库名/git tag名

然后运行:

./bench extract $CHECKOUTS
这一步会分别 checkout 具体的 tag 到同级的新目录里,然后开始编译:

./bench build   $CHECKOUTS
然后运行测试程序:

./bench time    $CHECKOUTS
一共有 65 个测试,测试项在 microbenchworks.pl 文件的大数组里定义了。 我在测试中发现,第 15/65 测试用例,在 nqp-moar 时会死循环运行,无法正常完成测试,已回报给作者。

最后运行结果对比评分:

./bench compare $CHECKOUTS
结果显示,moar 比 jvm 领先一些,比 perl5 还差着呢:

==> perl6-bench version 997c920 (ignoring startup time and compile time)
--- showing PEAK RATE (/s), TIMES SLOWER THAN FASTEST (x), and SUMMARY SCORES (skipping incomplete data)
