Vision filesystem - best size of the block factor

Problem:

What is the best size of the block factor for VISION files?

Resolution:

The blocking factor specifies the size of the blocks to be used by the file. Blocks are sized in 512 byte increments. Vision 5 files support blocking factors from 1 to 16 (16 = 8192 bytes). Vision 2, 3, and 4 files support blocking factors from 1 to 2.

When rebuilding a file, if the file is very large, or has a tree height of more than five, or key lengths in excess of 40 bytes, it is suggested to try larger blocking factors and perform some benchmarking to determine which larger block size improves performance.
