Page 20 of performance tuning guide states for midtier....
This setting confused me - could use some help here to help identify the optimal setting for performance. If you want to allocate more memory to the JVM and your hardware has more physical memory available, increase the file so that the mid tier can use the additional memory to better accommodate the caching of AR System forms for higher performance. This configuration parameter is specific to the cache and the value is based on empirical data that BMC has collected while profiling the mid tier under load. For each additional 700 MB, you can increase the by 1250 MB. You can determine the maximum number of in memory elements of each AR System type in the mid tier cache by multiplying the reference number by the weight factor as specified in . For example, the default maximum number of in memory active links is 6130 = 1250 * 4.904. This implies that you can adjust the weight factor based on your AR System application. For example, for applications with fewer active links, decrease the active links factor. I looked at the default setting on it is: arsystem.ehcache.maxElementsInMemory=10000 So this is a Win 2008 VM box Quad core with 12GB memory, and is dedicated to midtier. The ARS server it is connecting to is ARS 7.6.04 with ITSM full suite 7.6.04, so that is that is over 45,000 active links!!!! What would my calculation be, and what should I realistically set arsystem.ehcache.maxElementsInMemory to for the best performance????
