Ok, then when you say load all the file in one bufer, i suppose that i need
do some calls that they work over this buffer, and the application use these
calls  to read the file instead of the application (as now) work directly
over the API open,read etc. isn�t it?

Another ask, could this improvement  affect very much to the time of read?

thanks for all
