Hi Paul , The drop_caches is a command itself . To have it working you should create a cron job to issue the command all the time what is not so good . About the swappiness it works in my case because that parameters change the schedule about the swap out . The trick is the server will swap out but only if it really needed .
That will not solve the problem of the file cache but helps . If any one found the file cache solution please let me know .
