Blitz、smarty和php原生代码的运行效率对比

一、Blitz

1、从0-100循环，总流量已经超过7M，很可能会受网速的限制。
   服务器CPU利用率：85%左右，负载：1或2
   最繁忙的程序是nginx
   CPU利用率恢复到0%时，测试马上结束。

%webbench -t 90 -c 200 http://ict.sdcangyuan.com/test/blitz/test.php
200 clients, running 90 sec.
Speed=103998 pages/min, 7422003 bytes/sec.

%webbench -t 90 -c 300 http://ict.sdcangyuan.com/test/blitz/test.php
300 clients, running 90 sec.
Speed=103214 pages/min, 7354411 bytes/sec.
Requests: 154808 susceed, 14 failed.

2、改为从0-50循环：

%webbench -t 90 -c 300 http://ict.sdcangyuan.com/test/blitz/test.php
300 clients, running 90 sec.
Speed=114114 pages/min, 3711739 bytes/sec.

Speed=113617 pages/min, 3687560 bytes/sec.Requests: 170407 susceed, 19 failed.

二、smarty

1、CPU利用率： 100%， 负载：25左右
  最繁忙的程序是php-fpm
  CPU利用率恢复到0%时，仍然要等近两分钟才能结束测试
  300个连接，webbench会等会长时间也得不到结果。

下面的结果可能出错，因为同样的输出内容，在每分钟11W的时候，流量大约是不到4M，看后台，出现了大量的error，说明已经超出php的计算范围，这个时候应该出现了大量的错误页面：

%webbench -t 90 -c 250 http://ict.sdcangyuan.com/test/smarty/demo/index.php
Webbench - Simple Web Benchmark 1.5

250 clients, running 90 sec.

Speed=118555 pages/min, 955586 bytes/sec.
Requests: 177833 susceed, 0 failed.

减少并发数，可以看到结果差不多，每分钟1w，每秒在4百k左右：

继续加到200个并发，同时附上流量信息：

继续加到300并发，坚持了不到1分钟，nginx-error爆满：

三、php代码输出：

CPU利用率：55%左右

四、结论：

Blitz的速度大约是smarty的10倍，能达到php的直接echo方式的80%左右，性能相当不错了。

但是Blitz的变量值传递非常别扭，必须多一级数组，在数组循环的时候，竟然夸张地需要三级数组！相比来说，smarty的单级数组显得非常简洁和便于理解。
 

五、三种方式的源代码：

注：以上各个测试结果，均无Xcache加速器，下次测试有Xcache时的对比。

１、Blitz
php文件：

<?php
  $t = new Blitz();
  $t->load('{{ include("./test.tpl") }}');
  $arr = array();
  for ( $i = 0 ; $i < 50 ; $i++ ){
    $arr[]['number'] = $i;
   }
  $t->set(array('arr'=>$arr));

  $abc = "This is a Test template!";
  $t->set(array('abc'=>$abc));

  $title = "The Test Page of lsstarboy!";
  $t->set(array('title'=>$title));

  $t->display();
?>

tpl文件：

<html>
  <head>
   <title> {{ $title }} </title>
  <body>
   {{ $abc }} <br>
   {{ BEGIN arr }}
     <p>The number is {{ $number }} ! </p>
     {{ END }}
    <p> This is the end!!</p>
  </body>
</html>

２、smarty:
php文件：

<?php

require('../libs/Smarty.class.php');
$smarty = new Smarty;
$smarty->debugging = false;
$smarty->caching = true;
$smarty->cache_lifetime = 120;

$smarty->assign("title","The Test Page Of lsstarboy");
$smarty->assign("abc","This is a Test template!");

$arr = array();

for( $i=0; $i < 50; $i++ ) {
  $arr[] = $i;
}

$smarty->assign("arr",$arr);

$smarty->display('index.tpl');
?>

tpl文件：

<html>
  <head>
   <title>{$title}</title>
  </head>
  <body>
    {$abc}<br>
     {section name=test loop=$arr}
<p>The number is {$arr[test]} ! </p>
      {/section}
    <p>This is the end!!</p>
   </body>
</html>

３、php原生代码：

<?php
echo "\n";
echo "\n";
$title = "The Test Page of lsstarboy!";
echo "$title\n";
echo "\n";
echo "\n";
echo "This is a Test template!";
for ( $i =1 ; $i<50; $i++ ) {
  echo "The number is : " . $i . "!";
 }
 $abc = "This is the end!";
echo $abc;
echo "
\n";
echo "";
?>

----end----
