DOCUMENT:Q193814 22-OCT-2000 [sna] TITLE :Performance Improvements for APPC/CPIC Applications PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:4.0,4.0 SP1 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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.
