Data Cache

The data cache should be about 0.125 times the data file cache. However, certain calculations require a larger data cache size. If many concurrent users are accessing different data blocks, this cache should be larger.

In general, if you must choose between allocating memory to the data file cache or allocating it to the data cache, choose the data file cache if you are using direct I/O.
