My doctrine is Really Slow. Simple query and one second to get the result

问题

Here is my setup:
Windows Server 2008 R2
MySql 5.1.562
Php 5.3.2
Doctrine 1.2

Anybody have an Idea why my query is taking about one second to perform a simple query.

echo date("Y-m-d H:i:s", time()) ."::::::" . microtime(true)."<br />";

             $q = Doctrine_Query::create()
            ->from("Ordering")
            ->where("client_id = ?",array($_SESSION["UserID"]));

            $ResProduct = $q->execute();

echo date("Y-m-d H:i:s", time()) ."::::::" . microtime(true)."<br />";

Here is the result of the 2 echo to show you how long it's take to perform the query.

2011-04-21 01:48:24::::::1303364904.8051
2011-04-21 01:48:25::::::1303364905.8418

An other thing, there is no data in the database.

Edit
I Perform the query directly in the mysql console and get the result very quickly

mysql> select * from Ordering where client_id = 2;
+----+------------+-------+------+-----------+
| id | product_id | price | qty  | client_id |
+----+------------+-------+------+-----------+
|  7 |          1 |  0.89 |   20 |         2 |
+----+------------+-------+------+-----------+
1 row in set  (0.00 sec)

回答1:

Use microtime(true) instead of microtime_float()
Configure MySQL not to resolve IP's of connecting clients: http://dev.mysql.com/doc/refman/5.0/en/server-options.html#option_mysqld_skip-name-resolve
client_id = ?- why do you cast $_SESSION["UserID"] to array? I think this is unnecessary.

回答2:

First of all, your code doesn't seem wrong or anything.

Basically, though, your SQL query will typically look like this :

select *
from Ordering
where client_id = 123456

Which means that setting an index on the client_id column should probably help -- a lot, if there are many rows in that table.

A couple of relevant links, about that :

回答3:

Just out of curiosity have you attempted a RawSQL Query? We had an issue similar to this and it ended up being a DNS issue. Even though everything was supposed to be localhost the apache server was going external to resolve the address to mysql for some reason.
