Rakudo/Moar taking more memory at launch. #6448
Comments
From @SkarsnikAfter some test against various release of rakudo it appear that there is a huge step in the memory taken by rakudo/moar at launch. (after 2017.05) It was tested by reading the memory info in /proc/pid/statm (the number is in Kbytes) <AlexDaniel> committable6test: 92bd7e4f54a9^,92bd7e4f54a9,9658dd98c9dd8ec^^,9658dd98c9dd8ec say "/proc/$*PID/statm".IO.lines[0].split(/\s/)[5] * 4096 / 1024 |
From @AlexDanielNote that the tests on 92bd7e4^ and 92bd7e4 are not very related to this particular issue. To put simply: it went from 58628 to 138220 because of changes related to this commit (or maybe one or two commits before it): rakudo/rakudo@9658dd9 For Proc → Proc::Async issue see this ticket: https://rt.perl.org/m/ticket/show?id=131915 Bisect logs: On 2017-08-16 14:21:25, scolinet@gmail.com wrote:

The RT System itself - Status changed from 'new' to 'open' |
From @AlexDanielAlso, it's not any different on HEAD: <AlexDaniel> committable6test: 9658dd98c9dd8ec^^,9658dd98c9dd8ec,HEAD say "/proc/$*PID/statm".IO.lines[0].split(/\s/)[5] * 4096 / 1024 On 2017-08-16 14:27:37, alex.jakimenko@gmail.com wrote:

I can't reproduce such an sizable increase at HEAD or MoarVM/NQP/Rakduo: $ ./perl6-m -e 'say "/proc/$*PID/statm".IO.lines[0].split(/\s/)[5] * 4096 / 1024' |
From @AlexDanielInterestingly, I can't reproduce it as well… But the numbers are still higher than they were, so I guess the ticket is valid? Here's the output on all releases: https://gist.github.com/Whateverable/8687cceb1bfcf39e9818cef819d29391 I'd say we can close it once we go back to 50-ish.
