Bug #73265 [Com]: PHP7 dramatically slower in some cases

Edit report at https://bugs.php.net/bug.php?id=73265&edit=1 ID: 73265 Comment by: spam2 at rhsoft dot net Reported by: spam2 at rhsoft dot net Summary: PHP7 dramatically slower in some cases Status: Open Type: Bug Package: Performance problem Operating System: Linux PHP Version: 7.0.14 Block user comment: N Private report: N New Comment: ; [browscap] ; browscap = "/etc/php/browscap.ini" and the memory usage goes down that is the one from the servers and i think with that and my whole config in the last comment you should have a fine reproducer - will remove that from all machines now http://access.thelounge.net/harry/browscap.ini.txt Previous Comments: ------------------------------------------------------------------------ [2016-12-15 11:41:13] spam2 at rhsoft dot net since i have one instance with a normal memory usage maybe it depends on some specific part of my php.ini and you could even reprodcue the behavior with it easily on your machine?

If possible, can you rerun this with complete debug symbols? Assuming this is not just an artifact of broken symbols, the profile does show that most of the memory usage seems to come from zend_parse_ini_file(), which would be very unusual. (This could also explain why you're seeing a difference in 7.0.14, because there were some changes to the ini parser.) Can you please check whether running PHP without ini (-n) changes the situation? ------------------------------------------------------------------------ [2016-12-15 10:20:42] spam2 at rhsoft dot net extensions are also out of question - the tiny leeop-script from comment [2016-12-15 00:24 UTC] consumes 90 MB resident memory sceonds after start with all loadablke modules disabled [root@testserver:~]$ php -m [PHP Modules] bz2 Core date filter libxml mysqlnd pcre readline Reflection SPL standard xml zlib [root@testserver:~]$ ps aux | grep php dbmail 13097 0.5 1.4 128576 91064 ?

dot net no it won't - the binary is already compiled with --disable-huge-code-pages and keep in mind that this script is CLI, that setting affects opcode and as you can see in my previous comments for CLI opcache is even not loaded at all since the webservers have their own "php.ini" with PHPIniDir in the httpd.conf you have the whole script in my comment from [2016-12-15 00:24 UTC] and there is no sane reason to allocate 100 MB memory for that with some luck the php.spec makes it to that comment _________________ %global dist .fc%fedora.%(echo $(/usr/bin/date +%Y%m%d.%H%M)).rh %global phpver 7

<h.reindl@thelounge.net> - make sure that 'selftest' is using the intermediate-binaries in every case which became obvious on a machine running 7.1.0RC6 and building 7.0.14RC1 resulting in warnings about non-loadable extensions * Thu Nov 10 2016 Reindl Harald <h.reindl@thelounge.net> - update to PHP 7.0.13 * Sat Nov 5 2016 Reindl Harald <h.reindl@thelounge.net> - added patch to enable 'realpath_cache' with enabled 'open_basedir' we disable 'symlink' and 'link' for years and so CVE-2006-5178 has no point http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5178 * Sat Oct 15 2016 Reindl Harald <h.reindl@thelounge.net> - macro 'lto_build' enables link-time-optimization which increases build memory-usage combined with profile-guided-optimization dramatically but may improve performance for production builds - adds '--disable-gcc-global-regs' to configure-flags - adds '-flto -fno-fat-lto-objects -fuse-ld=gold -fuse-linker-plugin' to compiler and linker flags * Tue Oct 4 2016 Reindl Harald <h.reindl@thelounge.net> - add '--disable-huge-code-pages' to configure - performance seems to be unpredictable and in doubt faster without * Sat Oct 1 2016 Reindl Harald <h.reindl@thelounge.net> - macro 'break_build' starts a webserver on port 9000 with the temporary mod_php - script '/rpmbuild/PHP-PGO/profile.sh' supports as second param 'onlywebserver' instead profiling and kill it afterwards so we can use it's generate-logic for 'httpd.conf' and 'php.ini' with current locations in the working directory - remove '-funroll-loops' from compiler-flags - enabled for pgo-builds by '-fprofile-use' - add '-fno-exceptions -fvect-cost-model=unlimited -fipa-pta -fsemantic-interposition' to compiler flags - add '-fwrapv' to compiler flags to avoid https://bugs.php.net/bug.php?id=71201 - compiler-flags for documentation purpose: '-m64 -O3 -g0 -fopenmp -mfpmath=sse -pipe -fomit-frame-pointer -finline-functions -fstack-protector-strong

-Werror=format-security -Wno-pointer-sign -Wno-stack-protector' * Thu Sep 29 2016 Reindl Harald <h.reindl@thelounge.net> - change PGO sequence to use "make prof-gen; profile.sh; make prof-clean; make prof-use" - remove "-Wno-coverage-mismatch" from compiler flags - https://bugs.php.net/bug.php?id=73111 * Sun Sep 25 2016 Reindl Harald <h.reindl@thelounge.net> - add '-fmerge-all-constants' to compiler flags * Sat Sep 24 2016 Reindl Harald <h.reindl@thelounge.net> - add '-fno-strict-aliasing -fno-align-labels -fno-gcse' to compiler flags https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html Note: When compiling a program using computed gotos, a GCC extension, you may get better run-time performance if you disable the global common subexpression elimination pass by adding -fno-gcse to the command line * Fri Sep 23 2016 Reindl Harald <h.reindl@thelounge.net> - remove 'ftp', 'xmlrpc' and 'xslt' from build - rework call of test-suite to use default-settings instead cloned /etc/php.ini - removed useless options from configure now that we build with system-gd instead bundeled * Wed Sep 21 2016 Reindl Harald <h.reindl@thelounge.net> - define 'break_build' and local 'debug_build' macros to stop before tests and packaging - ship a 'debug-ini.php' with extensions and 'extension_dir' in the working directory - now we can use the built binaries without installing them on the system - usecase: temporary debug-builds or tests without running the whole build-process - output tells the needed env-export and how to call the binary export PHP_INI_SCAN_DIR=/home/builduser/rpmbuild/BUILD/php-7.0.11 CLI-BINARY: /home/builduser/rpmbuild/BUILD/php-7.0.11/sapi/cli/php * Sun Sep 18 2016 Reindl Harald <h.reindl@thelounge.net> - use 'profile-guided-optimization' instead of 'link-time-optimization' for memory/optimize-balance - define 'pgo_build' macro to disable 'profile-guided-optimization' temporary - we run scripted requests from a temporary webserver between make-stages to profile our application - benchmark our cms-system shows 7 percent higher performance for php7 - see: https://software.intel.com/en-us/blogs/2015/10/09/pgo-let-it-go-php - link with 'nodump' for enhanced security - remove 'mcrypt' from build (if-you-are-typing-the-word-mcrypt-into-your-code-you-are-doing-it-wrong) * Sat Sep 17 2016 Reindl Harald <h.reindl@thelounge.net> - move all extensions to sub-packages for minimzed dependencies * Tue Sep 6 2016 Reindl Harald <h.reindl@thelounge.net> - add '-fivopts -ftree-loop-if-convert -ftree-loop-if-convert-stores -ftree-loop-ivcanon' to compiler flags - explicit export of 'CC' environment variable with CFLAGS for optimized builds - cleanup ./configure params - use system-gd and disable some autotests (now supported without patches) - use system-libzip (now supported without patches) - remove skipped and failing autotests to keep focus on new regressions * Mon Aug 29 2016 Reindl Harald <h.reindl@thelounge.net> - cleanup spec-file to build more or less 'vanilla' php with only own optimizations - add 'php-httpd-dummy.conf' as temporary 'httpd.conf' at build-time for 'apxs' without hacks * Sun Aug 28 2016 Reindl Harald <h.reindl@thelounge.net> - add 're2c' to build-requires and '--enable-re2c-cgoto' to configure * Sat Aug 27 2016 Reindl Harald <h.reindl@thelounge.net> - build all extensions loadable to share them between httpd and cli * Fri Aug 19 2016 Reindl Harald <h.reindl@thelounge.net> - cleanup configure options - start with '--disable-all' and enable used features - build without unused modules - improves time for build and selftest - add '--disable-opcache-file' for smaller builds since we use only the shm-cache - add '-fno-math-errno -fira-loop-pressure -ftree-loop-distribution' to compiler flags
