Our problem is that we have file server and application server at the one server box. Thus there are continuous reads of files that placed on the file server disk arrays. Effectiveness of page cache in this case is not big because we have a big amount of files and absolutely uniform access to this files. And there are a some seldom used files on the applications partitions. This files can be effectively cached only if there is a way to keep them in the memory instead of recently read fileserver areas. Is there the way of tuning Linux page cache to accept pages from the separate device with higher/lower priority over pages from all other devices? Is there any solutions to it?
