XML in mySQL einlesen - Performanceproblem

[whine]

So, nu habe ich das mal mit den Prepared Statements versucht, aber das Ergebnis ist noch schlechter :( knappe 120s...

  
	 for ($i=1; $i <= $xml->Values; $i++) {  
  
    $sql_eintrag = "INSERT INTO exp_analyse_messwerte  
	        (id,  
	        Time,  
	        ".$xml->{"ChannelInfo1"}->Name.",  
		".$xml->{"ChannelInfo2"}->Name.",  
		".$xml->{"ChannelInfo3"}->Name.",  
		".$xml->{"ChannelInfo4"}->Name.",  
		".$xml->{"ChannelInfo5"}->Name.",  
		".$xml->{"ChannelInfo6"}->Name.",  
		".$xml->{"ChannelInfo7"}->Name.",  
		".$xml->{"ChannelInfo8"}->Name.",  
		".$xml->{"ChannelInfo9"}->Name.",  
		".$xml->{"ChannelInfo10"}->Name.",  
		".$xml->{"ChannelInfo11"}->Name.",  
		".$xml->{"ChannelInfo12"}->Name.",  
		".$xml->{"ChannelInfo13"}->Name."  
		) VALUES  
  
		(:id, :Time,  :ChannelInfo1, :ChannelInfo2, :ChannelInfo3, :ChannelInfo4  
		, :ChannelInfo5, :ChannelInfo6, :ChannelInfo7, :ChannelInfo8, :ChannelInfo9, :ChannelInfo10, :ChannelInfo11  
		, :ChannelInfo12, :ChannelInfo13)";  
  
	   $stmt = $dbc->prepare($sql_eintrag);  
	   $stmt->bindParam(':id', $id);  
	   $stmt->bindParam(':Time', $xml->{"M$i"}->Time);  
	   $stmt->bindParam(':ChannelInfo1', $xml->{"M$i"}->{"Ch1"});  
	   $stmt->bindParam(':ChannelInfo2', $xml->{"M$i"}->{"Ch2"});  
	   $stmt->bindParam(':ChannelInfo3', $xml->{"M$i"}->{"Ch3"});  
	   $stmt->bindParam(':ChannelInfo4', $xml->{"M$i"}->{"Ch4"});  
	   $stmt->bindParam(':ChannelInfo5', $xml->{"M$i"}->{"Ch5"});  
	   $stmt->bindParam(':ChannelInfo6', $xml->{"M$i"}->{"Ch6"});  
	   $stmt->bindParam(':ChannelInfo7', $xml->{"M$i"}->{"Ch7"});  
	   $stmt->bindParam(':ChannelInfo8', $xml->{"M$i"}->{"Ch8"});  
	   $stmt->bindParam(':ChannelInfo9', $xml->{"M$i"}->{"Ch9"});  
	   $stmt->bindParam(':ChannelInfo10', $xml->{"M$i"}->{"Ch10"});  
	   $stmt->bindParam(':ChannelInfo11', $xml->{"M$i"}->{"Ch11"});  
	   $stmt->bindParam(':ChannelInfo12', $xml->{"M$i"}->{"Ch12"});  
	   $stmt->bindParam(':ChannelInfo13', $xml->{"M$i"}->{"Ch13"});  
	  
	   $dbc->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );  
	   $stmt->execute();  
	  
	}

Es wird wohl nicht besser...
