I read the documentation. To begin with I have set cache_dir to 256MB and cache_mem also to 256 MB. Which takes the precedence? I guess the pages are stored/retrieved from the RAM. Does this setting mean that, once 256MB is reached in RAM it will start storing the pages in cache_dir? Thanks, Avinash
