php curl 中的gzip压缩性能测试

Jun 13, 2016 am 09:42 AM
curl gzip compression

前因:

 

  

 

1

请求接口次数很多,每日两亿多次,主要是有些接口返回数据量很大高达110KB(为了减少请求次数,将多个接口合并成一个导致的)。
后端接口的nginx已经开启gzip,所以做个测试,看看是否在请求时使用压缩解压

  

 

 

 

php CURL 的扩展安装这里就不说了

 

用到的curl的两个参数

 

 

//在http 请求头加入 gzip压缩
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept-Encoding:gzip'));

//curl返回的结果,采用gzip解压
curl_setopt($ch, CURLOPT_ENCODING, "gzip");

 

 

1、不使用压缩解压

 

 

$s1 = microtime(true);

$ch = curl_init();

for($i=0; $i

    $url="http://192.168.0.11:8080/xxxxx/xxxxx?";

    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_TIMEOUT, 3);

    $data = curl_exec($ch);

}

curl_close($ch);

echo  microtime(true)-$s1;

echo "\n";

  测试结果    请求100次平均耗时 2.1s   0.021s/次

 

   

 

2、使用压缩解压

 

 

$s1 = microtime(true);

$ch = curl_init();

for($i=0; $i

    $url="http://192.168.0.1:8080/xxxxx/xxxxx?";

    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_TIMEOUT, 3);

    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept-Encoding:gzip'));

    curl_setopt($ch, CURLOPT_ENCODING, "gzip");

    $data = curl_exec($ch);

}

curl_close($ch);

echo  microtime(true)-$s1;

echo "\n";

  测试结果    请求100次平均耗时 2.6s   0.026/次

 

 

 

结果

 

 

1、不使用压缩比使用压缩 请求一次快 5ms

2、千兆网,在局域网内传输这些数据大概是 0.7ms

The difference is tens of Kb for a small one and several dozen Mb for a large one. If it is uploaded to a cloud disk or paid space, it does not matter if the file is small. , if there are many files, the storage cost will be greatly increased. I studied it specifically and can learn from it if necessary. Compression level: 9-Extreme compression Dictionary size: 256 or 384, the more compressed the dictionary, the slower it is. The compression rate difference is larger before 256MB, and there is no difference in compression rate after 384MB. Word size: maximum 273 Parameters: f=BCJ2, test and add parameter compression rate will be higher
