A simple PHP script to test speed

Works with all versions of PHP: from 4.3 to 8.5

Dependencies

Required modules for full php testing:

  • pcre
  • mbstring
  • json
  • hash
  • dom
  • simplexml
  • intl
  • optional:
    • gd
    • imagick
    • zlib
    • bz2
    • brotli
    • lz4
    • snappy
    • zstd
    • igbinary
    • msgpack
    • uuid
    • memcache
    • redis
    • sqlite3
    • mysql/mysqli
    • pgsql

Usually they are already installed or "compiled" in php.

How to check it:

  • in console: php -m
  • or via function phpinfo() output

Minimum required memory

Is: 4Mb

Modules affecting test results

  • xdebug - can slow down most of the tests by half, and some related to error handling - by 10!
  • opcache - can cache the execution of functions, or throw out "not affecting execution" pieces of code
  • other opcode accelerators: xcache, apc, eaccelerator, etc.

Startup

0. Files

You need to put these files in one directory: bench.php, common.inc, php5.inc, php7.inc, php8.inc, igbinary.inc, intl.inc, msgpack.inc, compression-*.inc, php-options.php, php-gd-imagick-common.inc, php-gd.inc, php-imagick.inc, test.xml, UUID.php.

1. Through the console

Command:

Usage: bench.php [-h|--help] [-x|--debug] [-n|--dry-run] [-C|--dont-use-colors] [-J|--print-json] [-R|--print-raw] [-M|--print-machine] [-P|--print-only-total] [-d|--dont-recalc] [-D|--dumb-test-print] [-L|--list-tests] [-I|--system-info] [-S|--do-not-task-set] [-m|--memory-limit=130] [-t|--time-limit=600] [-T|--run-test=name] [-S|--skip-test=pattern]
        -h|--help               - print this help and exit
        -x|--debug              - enable debug mode, raise output level
        -n|--dry-run            - enable dry-run mode, do nothing, just to see output example
        -C|--dont-use-colors    - disable printing html-span or color sequences for capable terminal: xterm, *-color, *-256color. And not using it in JSON/machine mode.
        -J|--print-json - enable printing only in JSON format, useful for automated tests. disables print-machine.
        -R|--print-raw  - enable printing only raw values, no human readable forms, useful for automated eests.
        -M|--print-machine      - enable printing only in machine parsable format, useful for automated tests. disables print-json.
        -P|--print-only-total   - enable printing only total time but no intermediate test results.
        -d|--dont-recalc        - do not recalculate test times / operations count even if memory of execution time limits are low
        -D|--dumb-test-print    - print dumb test time, for debug purpose
        -L|--list-tests         - output list of available tests and exit
        -I|--system-info        - output system info but do not run tests and exit
        -m|--memory-limit <Mb>  - set memory_limit value in Mb, defaults to 130 (Mb)
        -t|--time-limit <sec>   - set max_execution_time value in seconds, defaults to 600 (sec)
        -T|--run-test <pattern> - run selected tests, test names from --list-tests output, can be defined multiple times
        -S|--skip-test <pattern>        - skip selected tests, test names pattern to match name from --list-tests output, can be defined multiple times```

Example: `php bench.php -m=64 -t=30`

The second option for passing values ​​for parameters is environment variables:

env PHP_MEMORY_LIMIT=64 PHP_TIME_LIMIT=30 php bench.php


Available variables:

- PHP_TIME_LIMIT=<Seconds>
- PHP_DEBUG_MODE=0/1
- DRY_RUN=0/1
- DONT_USE_COLORS=0/1
- PRINT_JSON=0/1
- PRINT_MACHINE=0/1
- PRINT_ONLY_TOTAL=0/1
- PHP_MEMORY_LIMIT=<Мб>
- DONT_RECALCULATE_LIMITS=0/1
- LIST_TESTS=0/1
- SYSTEM_INFO=0/1
- RUN_TESTS=test1,test2,...
- SKIP_TESTS=test1,test2,...

#### Extras (Utilities in Linux)

- You can set the priority of a process with the command `nice` - от -20 (high) до 19 (low). For example, priority 5: `nice -5 php bench.php`. Read `man nice`.
- You can set I/O priority with the command `ionice`. Example: `ionice -c3 php bench.php`. Read `man ionice`.
- You can bind script execution to the processor core with the command `taskset`. Example: `taskset -c -p 0 php bench.php`. Read `man taskset`.
- Вы можете комбинировать команды: `taskset -c -p 0 nice -10 ionice -c3 php bench.php`.

### 2. Through web servers (apache + php)

Just put in any php directory of the site available for execution, for example, in the root.

Then the script can be called with parameters, as from the console:
`curl http://www.example.com/bench.php?memory_limit=64&time_limit=30`
or via browser.

Available options:

- time_limit=Секунды
- debug_mode=0/1
- dery_run=0/1
- dont_use_colors=0/1
- print_json=0/1
- print_machine=0/1
- print_only_total=0/1
- memory_limit=Мб
- dont_recalculate_limits=0/1
- list_tests=0/1
- system_info=0/1
- run_tests=test1,test2,...
- skip_tests=test1,test2,...

### Accounting for hosting options

On many hostings, the `memory_limit` and `max_execution_time` parameters can be hardcoded.

In this case, the script will not be able to set the parameter values passed to it, at least not above the limits.

The script execution time will be recalculated according to the smallest resulting values.

### Other platforms

For example, on Raspberry Pi 2B, 3B and other similar boards, the execution speed is so slow,
that you have to specify the `-d -t 3600` options to make all the tests pass.

This applies to all ARM, MIPS, etc. As well as old AMD and Intel processors like Celeron, Atom, Duron, etc.

## Example script output

### Generic format

<<< WARNING >>> You need to disable Xdebug extension! It greatly slow things down! And mess with PHP internals. <<< WARNING >>> Execution time limit not droppped to '600' seconds! Script will have only '0' seconds to run. <<< WARNING >>> Extension 'xdebug' loaded! It will affect results and slow things greatly! Even if not enabled! <<< WARNING >>> Set xdebug.mode in php.ini / VHost or FPM config / php_admin_value or via cmd '-dxdebug.mode=off' option of PHP executable.
