使用php写入一个1GB大小的文件,检查硬盘的写速率,可能有一定误差,
建议还是使用专业的硬盘测试工具来检测
一般电脑读写在20M/s,这个测试要执行大概40-50s
1. [代码][PHP]代码
<?php 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 ".$usetime." seconds\n"; echo "speed :".$write_xiaolv." byte/s\n"; echo "speed :".$myga_xiaolv." m/s\n";
