The cache statistics information which is logged periodically, if the cache hits > 90%, the system does not necessarily requires to be retuned (increase the cache size). The messages about the cache being full is just a warning/hint to review your params if being seen frequently in the log file. The tuning depends on a number of factors including amount of memory available, throughput of orders, size of orders, etc.
