In order to obtain maximum benefit from distributed hybrid caching mode, it is important to set the following attributes correctly:

For example, a site might be set up as follows:

If no other item descriptors specify distributed hybrid caching, the GSACacheServerManager should set defaultItemCacheSize to 15 thousand. With this setting, it can keep track of all the user items that might be cached across all servers.

Setting the item cache size or defaultItemCacheSize too low is liable to incur increased network activity as follows:

Overall, the additional network activity can cause a slowdown in site performance that significantly overshadows the benefit of real-time updates. In general, if memory is limited, it is best to limit usage of distributed hybrid caching to item types that store a relatively small number of items, in order to minimize network overhead.
