效率测试：
插入：
<?php
include_once("gettime.php");
$btime = getmicrotime();
$i = 0;
$mem = new Memcache();
$mem->addServer('192.168.0.10', 11212);
$local_db = mysql_connect("192.168.0.208", "sunss", "123456");
if(!$local_db)
{
die('Could not connect: '.mysql_error());
}
$local_db_sel = mysql_select_db("test", $local_db);
mysql_query("set names utf8", $local_db);
while ( $i < 1000) {
$re_sql = "insert into urls (id,url) values ($i, 'www.gongchang.com')";
$res = mysql_query($re_sql, $local_db);
$i++;
}
mysql_close($local_db);
$etime = getmicrotime();
$runTime = round($etime - $btime, 4);
echo "runTime: ".$runTime."\r\n";
?>
