导读：代码如下: set_time_limit(0); $str = str_pad($str,512,"0"); $file = fopen("./temp","a+"); $i = 0; $bytes = 1000000000; $mygabyte = $bytes/1000000; echo "test start. waiting ..."; $starttime = time(); while($i $i += fwrite($file,$str); } $en

代码如下:

set_time_limit(0);
$str = str_pad($str,512,"0");
$file = fopen("./temp","a+");
$i = 0;
$bytes = 1000000000;
$mygabyte = $bytes/1000000;
echo "test start. waiting ...";
$starttime = time();
while($i < $bytes){
$i += fwrite($file,$str);
}

$endtime = time();
$usetime = $endtime - $starttime;
$write_xiaolv = $bytes/$usetime;
$myga_xiaolv = $mygabyte/$usetime;
echo "create 1GB file use time ".$usetime." secondsn";
echo "speed :".$write_xiaolv." byte/sn";
echo "speed :".$myga_xiaolv." m/sn";
