Determining optimum performance settings for a two-tier environment

Individual users running a two-tier environment can set the UNLOAD_TRIGGER_CEILING and UNLOAD_TRIGGER_FLOOR user preferences to best fit their individual needs. Users can use the default settings if they do not work with large amounts of data. Users can increase the value of the UNLOAD_TRIGGER_CEILING user preference if they work with large amounts of data, such as very large assemblies. Increasing the value delays the unloading of objects, improving performance. Users can determine the necessary settings by estimating an average object size of .5 KB. For example, with the UNLOAD_TRIGGER_CEILING default setting of 12000 KB, automatic unload occurs when approximately 24,000 objects are loaded. The 5,000 KB default setting for the UNLOAD_TRIGGER_FLOOR preference means unloading continues until approximately 10,000 objects remain in the unloadable memory area. These settings are adequate for most two-tier environments, including the default Teamcenter installation running only the Foundation template.
