Powerbuilder 12.5 - Slow web service response in Windows 7

Hi,

We are using a Frontend application built on Powerbuilder 11.5.

The webservice response time is good on XP after generating XML Serialization DLL's.

The same code built on Windows 7 using PB 11.5 also has good response time.

When tried to migrate the same to PB12.5 on WIN7 machine(32 bit), the application is becoming slow and also the webservice response time is too long even after using the XML Serialization DLL's.

This is impacting the performance of the application.

Could anyone please suggest if we have any solution to improve the webservice response time on WIN7 machine(32 bit) using PB v12.5.2 (Build 5751).

Appreciate your quick response on this

Thanks in advance,

Lavanya.
