[Xen-devel] overheads of having lots of pages granted at a time
Because of some windows limitations, I am going to have to pre-allocate page aligned buffer space for block device i/o at device setup, and copy data between the buffer space I get in each i/o request and the buffer space I''ve pre-allocated. My options are to either grant the pages at the time I allocate them, or to grant and ungrant each page as I submit the i/o request to xen.>From a performance point of view, is there any problem having lots ofpages granted when you aren''t using them?
