    Chapter 3. Optimizing communications performance Many factors can affect the performance of AS/400 application programs. T o achieve the best performance with your particular communications environment, you may want to review these topics: v Improving wide area network (W AN) performance. v Improving local area network (LAN) performance. v Improvin ...

    v For interactive environments, keep line use below 30% to maintain predictable and consistent response times. Exceeding 50% line use usually slows down response time. The line use can be measured with the AS/400 performance tools. v For large transfer environments, or for environments in which only a small number of users are sharing a line, incre ...

    processing a larger frame is only slightly more than the amount needed to process a smaller frame. If you use larger frames to transfer a single system message or block of data, decreases the total number of frames required to complete the transfer . v The values for IOP use in synchronous data link control (SDLC) environments do not necessarily in ...

    Chapter 4. Communications applications Communications applications that are used in an APPC (advanced program-to-program) environment are also available to be used in an APPN and HPR environment; only the method by which data is transported is changed.

    v Using larger sends for a given large transfer (record sizes) provides a higher application data rate and decreases CPU time. With the larger record size, the CPU has less processing to do because there are fewer application reads and writes to transfer the same amount of data. v If a value of *CALC is selected for maximum Systems Network Architec ...
