Oracle says "DB block size should be greater than OS block size for better performance of your database".

Hi list,

Here is from Oracle Manual :
"The operating system I/O size should be equal to or greater than the database block size".

And the benchmark said that greater O/S block size is better than small O/S block size.

My db_block_size now is 8K, and O/S block size is 512 bytes.

Should I increase the O/S block size for better performance ? Have you had the benchmark in your machine ?

Oracle 805, Sun OS 2.6, SGA 2 Gb, vxfs and ufs, OLTP and Batch application.

Thanks for any suggestion.
