Caches and object bindings

A table can be bound to a specific cache. If a table is not bound to a specific cache, but its database is bound to a cache, all of its I/O takes place in that cache.

Otherwise, its I/O takes place in the default data cache. The default data cache can be configured for large I/O. If your applications include some heap tables, they will probably perform best when they use a cache configured for 16K I/O.
