Doing a direct telnet to the memcached port, is that just for that one machine, or does it magically apply across all nodes?
Just one. There is no communication between different instances of memcached, even if each instance is running on the same machine. 15.5.5.26: Is memcached more effective for video and audio as opposed to textual read/writes memcached doesn’t care what information you are storing. To memcached, any value you store is just a stream of data. Remember, though, that the maximum size of an object you can store in memcached without modifying the source code is 1MB, so it’s usability with audio and video content is probably significantly reduced. Also remember that memcached is a solution for caching information for reading. It shouldn’t be used for writes, except when updating the information in the cache. 15.5.5.27: We are caching XML by serialising using saveXML(), because PHP cannot serialise DOM objects; Some of the XML is variable and is modified per-request. Do you recommend caching then using XPath, or is it better to rebuild the DOM from separate node-groups? You would need to test y
