Hello everyone.
I'm a sysop of Japanese Wikipedia. I'm going to delete many MediaWiki namespace pages that have same contents as betawiki. I think this work will make less operation cost.
I hava a question about caching and sever's overload. My colleague said that local wiki's MediaWiki namescape pages may make less overload of it's server, because these messages chaced and default messages are read from files.
I think, default messages are in PHP code files and these PHP codes may be compiled and cached between apache is alive. In other hand, messages saved in local Wiki are in DB, and they are got from DB server by all page requests.
Of course, even if local Wiki's MediaWiki namespace page don't exist, access to DB server is needed - because we don't know which it exist or not before access to DB server. Therefore non-existent of a MediaWiki namespace page makes a addional process.
But does this "addional process" mean just continuation to execute compiled codes without any reading from file or DB? This "overload" is same as zero, I think.
It makes more overload to delete system massages in local wiki's MediaWiki namespace pages?
Sorry for my poor English. Thank you.
