3 seconds for web service to call another web service
I am curious as to why a PowerBuilder WebService, written in PB12.5, calling any other webservice (PowerBuilder or otherwise), takes 3 seconds to connect.
Our PowerBuilder webservices, when called either from external sources, or from internal applications, connect almost instantly, and execute quickly. But if we have a webservice, that then tries to call any other webservice, that call takes 3 seconds (minimum time) to call.
Application -> Webservice to send an email (PB12.5) – sub-second response time
Application -> webservice (PB12.5) -> Webservice to send an email (PB12.5) – The webservice to webservice call takes 3 seconds. The email webservice is the same webservice in both cases.
PowerBuilder webservices are dot net webservices. (Deployed as .net, not written as .net).
Thanks for any insights!!
I'm not sure whether this is related, but I recall a report of performance problems with PB 12.5.1 calling webservices. I think 12.5.2 was supposed to have a fix for that.
