This can > help to improve the performance by about 85%. Do you have some statistics/some rough feeling how many consecutive bits are usually set in the bitmaps? Is it really just purely random or is there some granularity that is usually consecutive? IOW in real examples, do we have really large consecutive areas or are all pages just completely distributed over our memory? Thanks! -- David
