Not sure if this is related to addons at all or just the ingame code but something else related to the new guild history has been discovered..
MANY are experiencing brutally long 15-20sec delays using watshrines or porting in general due to the below setings in usersettings.txt.. The following changes fixes it.
Code:
SET GuildHistoryCacheAutoDeleteLeftGuilds "1"
SET GuildHistoryCacheMaxNumberOfDays_ava_activity "7"
SET GuildHistoryCacheMaxNumberOfDays_activity "7"
SET GuildHistoryCacheMaxNumberOfDays_milestone "7"
SET GuildHistoryCacheMaxNumberOfDays_trader "7"
SET GuildHistoryCacheMaxNumberOfDays_banked_currency "7"
SET GuildHistoryCacheMaxNumberOfDays_banked_item "7"
SET GuildHistoryCacheMaxNumberOfDays_roster "7"
