The problem is that each PharData::addFile() flushes the archive, i.e. completely writes it back to disk. That takes time... ------------------------------------------------------------------------ [2020-11-23 12:33:59] maggus dot staab+php at googlemail dot com thx for coming back to me. 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 ------------------------------------------------------------------------ [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? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
