GOAL:
What the -Mr (Record Buffer Size) does?
GOAL:
How much memory is is used to load a record in the client memory
FIX:
The -Mr is used as the DEFAULT size for a record buffer.
When the client reads a record into its memory, if it does not know the size, it gets a buffer of -Mr size. It then attempts the read with that size. If -Mr is not large enough, it has to get another buffer of the actual required size, and re-issue the record read.
Therefore, setting a too small value to the -Mr can cause poor performance.
