PHP MySQL Select＆amp;每分钟更新所有行（~10000）

Question

我想从每行中选择三件事，然后更新每一行。 代码每分钟运行一次cronjobs。 但是，在可接受的时间范围内更新所有行需要很长时间。 这就是它现在的样子：

    $update_query = "UPDATE game_1 SET amount=? WHERE name=?";
    $count_query = "SELECT COUNT(*) FROM game_1";

    $stmt = $conn->prepare($count_query);
    $stmt->execute();
    $stmt->bind_result($count);
    $stmt->fetch();
    $stmt->close();

    echo $count . "\n";

    $select_query = "SELECT name, speed, amount FROM game_1 LIMIT ?,1";

    echo $select_query . "\n";

    while($count != 0)
    {
        $stmt = $conn->prepare($select_query);
        $counted = $count-1;
        $stmt->bind_param("i", $counted);
        $stmt->execute();
        $stmt->bind_result($name, $speed, $amount);
        $stmt->fetch();
        $stmt->close();
        $stmt = $conn->prepare($update_query);
        $newamount = $amount+$speed;
        $stmt->bind_param("is", $newamount, $name);
        $stmt->execute();
        $stmt->close();
        echo "Updated row " . $count . "\n";
        $count--;
    }

    exit;

是否有更好的表现？
