PHP 7.1:

Time per request: 157.844 [ms] (mean)
Time per request: 3.157 [ms] (mean, across all concurrent requests)

PHP 7.2 JIT:

Time per request: 1.080 [ms] (mean, across all concurrent requests)

These results are very unlikely. I'm 95% sure your benchmark is broken.
My first guess would be that you're benchmarking PHP + JIT against PHP
without opcache. Please share the relevant (opcache-related) portion of
the php.inis you used
no they are not - since i build RPM packages and even the whole
spec-file is unchanged, only the tarball changed and the build is highly
optimized i can assure you for 100% that i compare PHP 7.1.5RC1 with
https://github.com/zendtech/php-src downloaded today
maybe the PGO-profiling running autotests and fuzzy-calls on the whole
application as well as 2000 cms-requests combined with the compiler
flags improves the JIT itself
without opcache the results for 7.1.5 are *dramatically* slower
and i repeated the test upgrade/downgrade packages and run "ab" multiple
times on that machine - attached the "php.spec" which is used for the build
in just downloaded the zip from https://github.com/zendtech/php-src,
renamed it to "php-7.2.0", made a tar.xz archive, changed the version on
teh frist line in the spec file and fired the build/profiling - nothing
else changed

%changelog
* Tue May 2 2017 Reindl Harald <h.rei...@thelounge.net>
- add '--enable-opcache-jit' to configure for tests with experimental jit-branch
* Thu Apr 13 2017 Reindl Harald <h.rei...@thelounge.net>
- update to PHP 7.0.18
* Tue Mar 14 2017 Reindl Harald <h.rei...@thelounge.net>
- update to PHP 7.0.17
* Thu Feb 16 2017 Reindl Harald <h.rei...@thelounge.net>
- update to PHP 7.0.16
* Wed Jan 18 2017 Reindl Harald <h.rei...@thelounge.net>
- update to PHP 7.0.15
* Tue Jan 17 2017 Reindl Harald <h.rei...@thelounge.net>
- add '-fdevirtualize-speculatively -fgraphite-identity -floop-block -floop-unroll-and-jam' to compiler flags
- remove openssl-tests because https://bugs.php.net/bug.php?id=73609 makes me sick
- add fedora systzdata-patches
- add '-fstrict-aliasing -Wstrict-aliasing' to compiler-flags
- add '--enable-huge-code-pages' to configure
- build 'readline' as loadable extension (interactive shell)
* Sun Jan 8 2017 Reindl Harald <h.rei...@thelounge.net>
- command 'rpmbuild -bb php.spec --with production' will tune for current hardware while default to 'sandybridge'
- build-cpu-architecture is now part of the package-version to move optimized builds to different repos
- remove all optimizations when 'debug_build' is enabled and add 'valgrind' param to 'profile.sh'-call
- add '-ftree-loop-im' and '-fvariable-expansion-in-unroller' to compiler flags
* Tue Dec 27 2016 Reindl Harald <h.rei...@thelounge.net>
- build 'intl' as loadable extension
- add 'libicu-devel' to build-requires
- run profiling-script after compile a debug-build to fetch memleak-warnings
- build 'bz2' as loadable extension
* Thu Dec 8 2016 Reindl Harald <h.rei...@thelounge.net>
- update to PHP 7.0.14
* Thu Nov 10 2016 Reindl Harald <h.rei...@thelounge.net>

* Sat Nov 5 2016 Reindl Harald <h.rei...@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

* Sat Oct 15 2016 Reindl Harald <h.rei...@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
* Sat Oct 1 2016 Reindl Harald <h.rei...@thelounge.net>
- macro 'break_build' starts a webserver on port 9001 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
* Thu Sep 29 2016 Reindl Harald <h.rei...@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
- add '-fmerge-all-constants' to compiler flags
* Sat Sep 24 2016 Reindl Harald <h.rei...@thelounge.net>
- add '-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.rei...@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
* Wed Sep 21 2016 Reindl Harald <h.rei...@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.rei...@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)
- move all extensions to sub-packages for minimzed dependencies
- 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
- 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
- cleanup spec-file to build more or less 'vanilla' php with own optimizations
- add 'php-httpd-dummy.conf' as temporary 'httpd.conf' at build-time for 'apxs' without hacks
- add 're2c' to build-requires and '--enable-re2c-cgoto' to configure
- build all extensions loadable to share them between httpd and cli
- 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 because we only use the shm-cache
- add '-fno-math-errno -fira-loop-pressure -ftree-loop-distribution' to compiler flags
