I justed did a blackfire profile and measured the non-profiled timings on a few more servers and php-versions. have a look at the readme: https://github.com/staabm/php-phardata-benchmark I don't have a server at my disposal where the latest php version is available. everything I have is ubuntu LTS bound Previous Comments: ------------------------------------------------------------------------ [2020-11-23 12:02:42] cmb@php.net Could you please check the performace for PHP 7.4.12? And also, could you check that with the blackfire extension? ------------------------------------------------------------------------ [2020-11-22 11:40:01] maggus dot staab+php at googlemail dot com Description: ------------ while working on one of our projects we figured creating TAR files with PharData would be a great fit, because its php-src builtin. it turns out though creating TAR Files with PharData is super slow, compared to userland php implementation. we see 10x slower performance. see a benchmark and repro script at https://github.com/staabm/php-phardata-benchmark Expected result: ---------------- PharData should be at least on paar with php userland implementations Actual result: -------------- its slow ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80399&edit=1
