The dataserver binary builds the master device (located in $SYBASE/ASE-15_0/bin). The dataserver command allows you to create master devices and databases with logical pages of size 2KB, 4KB, 8KB, or 16KB. Larger logical pages can provide benefits for some applications:
You can create longer columns and rows than with smaller page sizes, allowing wider tables.
Depending on the nature of your application, you may improve performance, since Adaptive Server can access more data each time it reads a page. For example, reading a single 16K page brings 8 times the amount of data into cache as reading as a 2K page; reading an 8K page brings in twice as much data as a 4K page, and so on.
However, when you use larger pages, queries that access only one row in a table (called point queries) use rows that occupy more memory. For example, each row you save to memory in a server configured for 2k logical pages uses 2k, but if the server is configured for 8k logical pages, each row you save to memory uses 8k.
Analyze individual cases to verify whether using logical pages larger than 2KB is beneficial.
