PHP7.1 is fast(?)

Transcript

1. PHP7.1 is fast(?)

2. name: ͍ͩ͠͡ΎΜ͍ͪ (Ishida) nick: uzulla (͏ͣΒ) fun: PHP and !

3. conclusion 7.1 is fast ! (but any evidence here)

4. need benchmark !!

5. by the way... php can't to be standalone httpd. right?

   (php -s is for only development use) (btw, hhvm can be !) If will benchmark with apache/nginx, that is unfair(???)

6. use "ReactPHP"! (use libevent) standalone httpd(and other), that written by

   PHP!

7. Test Enviroment 4 VPS (Vultr, $5/mo) 4 1Core 4 1GB

   mem 4 ubuntu 16.10 4 PHP7.1.2

8. Write git clone code. 4 httpd, written by php 4

   https://github.com/uzulla/ ReactPHP_PostSupportSample 4 include monolog, twig(template engine.)

9. <?php require_once 'vendor/autoload.php'; $loader = new Twig_Loader_Filesystem(__DIR__.'/templates'); $twig = new

   Twig_Environment($loader, [ 'cache' => __DIR__.'/twig_cache', ]); $access_log = new \Monolog\Logger('access'); $access_log->pushHandler(new \Monolog\Handler\StreamHandler(__DIR__.'/access.log', \Monolog\Logger::INFO)); // app $app = function (\Uzulla\React\Http\Request $req,\React\Http\Response $res) use ($twig, $access_log) { $path = $req->getPath(); $method = $req->getMethod(); $access_log->addInfo("{$method}\t{$path}"); $params = [ 'params'=>$req->getParams(), 'query'=>$req->getQuery() ]; if($method === 'GET' && preg_match('|\A/\z|u', $path)){ $res->writeHead(200, ['Content-Type' => 'text/html']); $res->end($twig->render('index.twig',$params)); }elseif($method === 'POST' && preg_match('|\A/\z|u', $path)){ $res->writeHead(200, ['Content-Type' => 'text/html']); $res->end($twig->render('index.twig',$params)); }else{ $res->writeHead(404, ['Content-Type' => 'text/html']); $res->end($twig->render('notfound.twig')); } }; // build reactor $loop = React\EventLoop\Factory::create(); $socket = new React\Socket\Server($loop); $http = new \Uzulla\React\Http\Server($socket); $http->on('request', $app); $socket->listen(8080); echo "running...\n"; $loop->run();

10. $ git clone THAT $ composer install $ php boot.php

    listen...

11. ab(apache bench) 4 ab -n 10000 -c 10 http://127.0.0.1:8080/

12. Requests per second: 3477.39 #/sec

13. okay, try more concurrent connection.

14. 5000 concurrent 4 ab -n 10000 -c 5000 http://127.0.0.1:8080/

15. fail 4 socket: Too many open files (24)

16. ok, ab's limits. try another tool. apt install wrk 4

    https://github.com/wg/wrk

17. wrk 4 wrk -c 5000 -d 5 http://127.0.0.1:8080/

18. Requests/sec 98.16

19. tooooo slow, hmmm, concurrent overkill? try 1000 concurrent (same as

    ab's test).

20. 4 wrk -c 1000 -d 5 http://127.0.0.1:8080/ 4 Requests/sec: 83.17

21. !

22. okey, wrk is dosen't work. try with httperf ! 4

    https://github.com/httperf/httperf

23. httperf 4 httperf --port=8080 --server=127.0.0.1 -- rate=2800 --num-conns=10000 --hog

24. Request rate: 2799.6 req/s

25. seems good. but, is this correct? I need try more

    tools !

26. siege 4 siege -c 100 http://127.0.0.1:8080/ 4 Transaction rate: 393.35

    trans/sec

27. Untrustworthy... (Of course, these bench mark tools are more trustworthy

    than weird httpd.)

28. all results (?) ab: 3477.3 #/sec wrk: 98.1 req/sec httperf:

    2799.6 req/s siege: 393.3 trans/sec

29. me: I'm screwed lestrrat ( a.k.a daisuke maki): Why don't

    you write a bechmarker yourself ? me: what?

30. me: OK, I'll write tools! (at YESTERDAY 11:36 pm)

31. I wrote "benchmark.php" !! (ta daaa!)

32. <?php $c = 10000 ; $target = "http://127.0.0.1:8080" ; $start_usec

    = microtime(true); for( $i=0; $c>$i; $i++ ){ $res = file_get_contents($target); } $used_time = (microtime(true) - $start_usec) ; echo ceil( 1/( $used_time/$c ) ); echo "req/sec";

33. haha... yes, just kidding. let's play.

34. (unreliable) result 4 3,731 req/sec

35. I can't believe this result. (faster than ab ;lol) it's

    not bad. but ...

36. I thought, this is slow benchmark tool. ! I want

    more faster". but how? I need concurrent.! but, this is php. (curl_multi ? yes...but... ) OK! WE NEED FORK! !

37. <?php $max_worker = 10; $c = 10000; $c_ = $c/$max_worker;

    $target="http://127.0.0.1:8080"; $start_usec = microtime(true); $pids=[]; for($x=0;$max_worker>$x;$x++){ $pid = pcntl_fork(); if ($pid == -1) { die("fork failed");} else if ($pid) { $pids[]=$pid; } else { for($i=0;$c_>$i;$i++){ $res = file_get_contents($target); } exit; } } foreach($pids as $pid){ pcntl_waitpid($pid, $status); } $used_time = (microtime(true) - $start_usec) ; echo ceil( 1/( $used_time/$c ) ), "req/sec";

38. 2881req/sec (no fork ver 3,731 req/sec)

39. no no, more slow !!! !

40. ! need more core!!!

41. create 4core 8GB mem server !

42. benchmark.php 4147req/sec fork_benchmark.php 3995req/sec

43. NO! why fork ver is more slow!? !

44. my httpd is BAD, that is why!!! ! I use

    nginx to benchmark my benchmark!! !

45. result(?) with nginx 4 benchmark.php 4 6817req/sec 4 fork_benchmark.php 4

    13730req/sec

46. OK! 4 fork ver faster than not fork ver!!

47. ( what is ok? )

48. meanwhile in apache bench... 4 ab -c 10 -n 10000

    http://nginx/ 4 Requests per second: 15273.21

49. compare own tool and ab. 4 fork_benchmark.php: 4 13,730 req/sec

    4 ab: 4 15,273.21 #/sec

50. okey!(?)

51. conclusion my bench (written by PHP) 0.9 times faster than

    AB !! ( DISCLAIMER, THIS RESULT IS REAL RESULT. BUT JUST PLAYING.)

52. OK !!

53. "what is ok?" (now 2:12 am)

54. Other benchmarks. 4 php7.1.2 with my_httpd + fork_bench.php(c:10) 4 3858req/sec

    4 php5.6.30 with my_httpd + fork_bench.php(c:10) 4 2425req/sec 4 hhvm3.18.1 with my_httpd + fork_bench.php(c:10) 4 2377req/sec 4 (but, hhvm w/o libevent)

55. conclusion PHP7.1 is fast (1.6x faster than 5.6 (at this

    test))

56. (REAL) conclusion USE RELIABLE TOOLS USE NGINX DON'T USE PHP

    FOR WRITE A BENCHMARK TOOL

57. but fun. PHP is waiting New Challengers ..... FIN

58. //NEXT use pthread;
