The gzip compression performance test in PHP curl

Antecedent:        1 Request interface many times daily, 200 million times a day, mainly some interface return data volume is large up to 110KB (in order to reduce the number of requests, the combination of multiple interfaces into one result). <br> back-end interface Nginx has been opened gzip, so do a test to see if the request to use compression decompression       PHP CURL extension Installation Here is not said   used in the CURL two parameters    //Add gzip compression <br>curl_setopt ($ch, Curlopt_httpheader, Array (' Accept-encoding:gzip ') to the HTTP request header); Curl returns the result, using gzip decompression <br>curl_setopt ($ch, curlopt_encoding, "<span style=" line-height:1.5; " 　 >gzip</span> ");   1, do not use compression decompression     $s 1 = microtime (true); $ch = Curl_init (); For ($i =0 $i <100; $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 ($ch); Echo  microtime (True)-$s 1; 　　echo "\ n"; Test results     Requests 100 times average time 2.1s   0.021s/times         2, using compression decompression     $s 1 = microtime (True) ;$ch = Curl_init (); For ($i =0 $i <100; $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 ($ch); Echo  microtime (True)-$s 1; 　　echo "\ n"; Test results     Requests 100 times average Time 2.6s   0.026/times       result     1, no compression than using compression request one faster 5ms 2, gigabit Network, in LAN incoming This data is probably 0.7ms
