Redis pipeline 在连续一万次插入操作测试中的使用中
如下代码运行后的结果是

  10000noPipeline:0.36595296859741s
  10000yesPipeline:0.016739130020142s
 

可以看出pipeline确实可以节省很多时间

<?php
/**
 * 这里我想测试下Redis pipeline的功能

    yesPipeline($redis);
    $end_time = microtime(true);

    echo "yesPipeline:".($end_time - $start_time)."s\n";;
