In an ideal world we'd have variable sized pages ... but since most arcthitectures have no h/w support for these it may be a long time before that comes to Linux. In a fixed page size world the right page size to use depends on the workload and the capacity of the system. When memory capacity is measured in hundreds of GB, then a larger page size doesn't look so ridiculous. -Tony -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
