Is TNSPING = 1000ms OK? Oracle says it is

Hi

I have a server (Windows Server ) with Oracle EE with databases using
Data Guard. (Oracle 9iR2)

There is an Oracle Listener (1521) and Oracle Data Guard Listener (1748) on a 
server.

If I TNSPING both ports, I get the following results.

Port    Response Time
----   --------------
1521    20 ms
1748    1000 ms

So I asked Oracle support and the reply - 

The Data Guard needs to do lots of stuff and 1000 ms is OK. 

What?  That is x50 slower than a normal tnsping to 1521 
and they tell me that this is acceptable?    


What do you think?
What times do you get for tnspinging a Data Guard port?
(The are no network QoS/packet shaping ) 
Even doing a loopback tnsping on the same server gives the same result.



Here are the outputs:





tnsping (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 
server1dr)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = 
DRTEST.world)))  5
