mysql空间速度慢
答案


请教大家一个问题,我花钱租了个mysql的服务器虚拟空间,发现速度很慢。我用最简单的表格查询,每查询一次都要用5秒钟以上,这正常吗?

数据库里,只有一个表格和两条记录,
下面是我的测试代码:

$stime = microtime(true); // 获取程序开始执行的时间

$db_ip = "61.152.93.83";

$db_user = 'blinnes';

$db_pass = 'ji64Edfw2';

$cn = mysql_connect($db_ip, $db_user, $db_pass);

$db = mysql_select_db("blinn");

$sql = "select * from `test`";

mysql_query("set names gb2312");

$rs = mysql_query($sql);

while ($row = mysql_fetch_array($rs))

{

echo "mysql! - " . $row['名称'] . "|" . $row['数量'] . "
";

}

mysql_close($cn);

$etime = microtime(true); // 获取程序执行结束的时间

$total = $etime - $stime; // 计算差值

echo "(mysql版)此次查询执行时间:" . $total . "秒";

?>

估计就是Fising说的数据库和PHP不在一台服务器的原因,让他们把数据库空间和php空间弄到同一台服务器上,速度就快了。
