Dear WikiMedia,We are using Action API to get recent change updates from www.wikidata.org:https://www.wikidata.org/w/api.php?action=query&format=json&continue=&list=recentchanges&rclimit=500&rcnamespace=0%7C2%7C4%7C6%7C10%7C14%7C120%7C122%7C828&rcprop=comment%7Cflags%7Cids%7Cloginfo%7Coresscores%7Csizes%7Ctags%7Ctimestamp%7Ctitle%7CuserBut we've found that this API become very slow recently, the response time of one API request is between 15s ~ 25s.Sometimes the API returns an empty recent change list:Other times the length of the response recent change list is always between 35~37, even if we set the rclimit parameter to 500.Is there any changes related to www.wikidata.org recently?Sincerely,Wenjie
