Test code

for($i=0;$i<100000;$i++){
  $packMsg = msgpack_pack($msg);
}
echo &#39;pack len:&#39;.strlen($packMsg)."\r\n";
$end = microtime(true);
echo &#39;run time:&#39;.($end-$start).&#39;s&#39;."\r\n"; 
echo &#39;memory usage:&#39;.(memory_get_usage()/1024)."KB\r\n";

Analysis and comments

The basic results of online searches are all (presumably versions before php7)

运行速度 serialize<json<msgpack
长度  serialize>json>msgpack
内存消耗 serialize<json<msgpack //不过近乎一致

Run in php7, the results are as follows

运行速度 serialize<msgpack<json  //这里出现了变化
长度  serialize>json>msgpack
内存消耗 serialize<json<msgpack //不过近乎一致
