The dominant factor affecting Meridian application server responsiveness, assuming that sufficient physical and virtual memory is available, is the server’s CPU. Upgrading the CPU to a faster clock speed resolves most performance problems. However, it should not be considered a cure-all, and the other areas described in this guide should also be optimized for peak performance. When you are selecting a new Meridian application server computer, the fastest available CPU (one or more) provides the greatest value.
To determine if the server’s CPU is limiting performance, monitor the AMEDMW instance of the Process object with Performance Monitor as described in Configuring the Windows Performance Monitor.
Consider using the multi-threaded database engines described in Hypertrieve Database Engine. We do not recommend setting the Processor Affinity of the Meridian service processes on multiprocessor servers, which can decrease overall performance. Windows symmetric multiprocessing performs better processor load balancing.
In environments where SQL Server or Oracle is used as the Meridian DBMS or multiple large Hypertrieve vaults are frequently accessed by users, it is possible to improve overall performance by hosting Meridian on a server with more processor cores. Although Meridian cannot directly take advantage of more than one core, due to Windows symmetric multiprocessing ability, Windows will assign SQL Server or Oracle processes to the other cores. Windows can also assign individual Meridian vault database engines to the other cores if the Meridian CopyDLL option is enabled as described in Configure the CopyDLL Setting. With system processes divided among the available processors, overall processing throughput is increased.
