It will never be disk-bound unless the site is tiny and/or has too little RAM. The files can be expected to remain in the page cache perpetually as long as there's a constant stream of requests coming in. If the site is tiny, performance isn't a big issue (at least not for the site operators). If the server has so little free RAM that a file that's being read every few minutes and is under a megabyte in size is consistently evicted from the cache, then you have bigger problems to worry about. _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
