Performance Improvements for APPC/CPIC Applications

• Microsoft SNA Server, versions 4.0, 4.0 SP1

SUMMARY

Various performance improvements have been implemented within the SNA Server client (Snadmod.dll, Snalm.dll) and the Win32 APPC .dll (Wappc32.dll) to help maximize performance of APPC or CPIC applications. Improvements include:

• More efficient internal buffer allocation/deallocation within the SNA client software.



• Reduced thread usage when an application calls RECEIVE_ALLOCATE more than once and specifies the same TP name.



• Improved routing of incoming FMH-5 to the SNA client computer where the invokable TP is running.



• Improved SNA Server performance while handling an incoming FMH-5 Attach request.

RESOLUTION
