Timeout - or not!

hi all

Forgive a poor newbie if this is a silly question.  I am executing a web service which times out before the results can be returned.  I then submit the request again, and it returns pretty much instantly - soapUI shows a response time of 251ms.  However the returned data includes the query run time recorded on the server, and this shows 58 seconds.

Any idea what is going on here?

thanks!
