Edit report at https://bugs.php.net/bug.php?id=76867&edit=1 ID: 76867 Updated by: nikic@php.net Reported by: ivokund at gmail dot com Summary: Extremely slow performance Status: Open Type: Bug Package: Performance problem Operating System: Ubuntu 18.04.1 LTS PHP Version: 7.2.9 Block user comment: N Private report: N New Comment: We changed USE_ZEND_ALLOC_HUGE_PAGES to control the use of transparent huge pages as well at some point (it's disabled by default now), so I'm closing this issue. Previous Comments: ------------------------------------------------------------------------ [2019-05-09 08:21:45] nivetha0728 at gmail dot com Get the PHP support ------------------------------------------------------------------------ [2018-10-03 08:53:48] sjon at hortensius dot net @requinix - USE_ZEND_ALLOC_HUGE_PAGES should control Zend's core allocation, see https://github.com/php/php-src/commit/945a661912612cdecd221cd126feda7d4335c33c. Since that doesn't work, this issue might be caused by the opcache which has a separate setting (opcache.enable_huge_code_pages), see https://github.com/php/php-src/commit/669f0b39b184593e01e677360fd79b2b63058ca0 @rhsoft - while hugepages are faster, misses are costly (again, see https://bugs.php.net/70984 ) ------------------------------------------------------------------------ [2018-09-20 12:57:59] spam2 at rhsoft dot net i don't get the impact completly huge pages are assumed to be faster and PHP also has --enable-huge-code-pages for opcache - would it be better to change that also to --disable-huge-code-pages while not sure if that is using transparent or "dedicated" huge-pages which won't work anyways without epxlicit admin dance (see mysql and huge pages) ------------------------------------------------------------------------ [2018-09-20 12:51:20] lyrixx at lyrixx dot info Hello, I got the same problem. I don't know why since I just update PHP to 7.2.10 Anyway, I executed hugeadm --thp-never and the issue seems to be fixed. ------------------------------------------------------------------------ [2018-09-13 15:52:35] ivokund at gmail dot com I disabled huge pages with "hugeadm --thp-never" and the problem disappeared instantly. I'm happy now, so if this is not a PHP issue then please close the issue.
