[webservices] station metadata text output problem

[Chad Trabant]

Bummer, even that sentence is incorrect.  If the response level (level=resp) is requested with ws-station it requires database access and can be a little slower.

To add a bit more, the extraction from the database for the vast majority of requests is very fast.  The upshot is that it might be very difficult for a user external to the DMC to notice the difference.

Sorry for the junk email.

The XML itself should be returned quite quickly, particularly if no secondary origins, magnitudes or arrivals are requested (that requires database access).  Please let us know if you observed slow transmission of the XML.

The text output has excellent performance and it general works very well. However I noticed a problem with the station level text output for network IC station QIZ.
