new NOAAPORT NIDS products

I have a question about rhe new NOAAPORT NIDS products.  Is it normal for
the
new products to be 3-6 minutes old or do we have an I/O problem.
The time stamp on the N0R files is only 1 minute older than the product
time, but the other products like NET and N1P are 4-7 minutes old.
Is this normal?  I have cut back the data we are writing to disk
to just N0R,N0V,N0S,N1P,NTP,NET,NVL.

Thanks,
Robert
