The information in this article applies to:

- 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
==========

Microsoft has produced an update to SNA Server 4.0 which improves performance
for APPC or CPIC applications. This update is included in the latest SNA Server
version 4.0 U.S. Service Pack. For information on obtaining this Service Pack,
