Not surprisiing at all, Stripe Set is the amount of Data a RAID moves for every read/write so if you have 16 KB or 4KB you still move 64KB each time but with much less usable Payload per transfer go for a Stripsetsize of 16 KB and a Pagesize of 16KB for best match -- Mit freundlichen Grüssen Hannes Streicher mailto:[email protected] ------------------------------------ ------------------------------------ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.
