Database Cache Size (MB) is the amount of system memory, in megabytes, used by the database cache manager to hold commonly used information from the database file(s) to prevent file operations. If the database cache size seems to be too small for optimal performance, and there is very little available memory on the system (see Memory/Available Bytes), an increase of memory in the system may increase performance. If there is a large amount of available memory on the system, and the database cache size is not growing beyond a certain point, the database cache size may be capped at an artificially low limit. An increase in this limit may increase performance.
