The memory alignment boundary parameter determines the memory address boundary on which data caches are aligned.

Some machines perform I/O more efficiently when structures are aligned on a particular memory address boundary. To preserve this alignment, values for memory alignment boundary should always be powers of two between the logical page size and 2048K.

NoteThe memory alignment boundary parameter is included for support of certain hardware platforms. Do not modify it unless you are instructed to do so by Sybase Technical Support.
