Hi developpers,
I would like to know information about OS virtual memory page and your
BTree node. Theoriticaly, BTree perform better if his size node is the
same that OS page (the unit of transfer between main memory and disk).
This way, it take just one disk access to load in memory a BTree node.
Do you use this strategy for your BTree node? If yes, could you explain
to me how it works please? How can you be sure that reading a node in
memory will take just one disk access? Do you make special call to OS
file system?
Thanks for your time.
Jean
