Hey there,
Since I couldn't figure it out or find an answer, resorting to the forums, maybe some of you figured it out.
Since latest patch, auction creation time (posting single item to the trader) have significantly grown. It takes up to 10 seconds in worst cases to post a single item.
It sometimes also happens when you open up a container so i figured it's somewhat connected to either - inventory management addons or loading guild history.
I've tried figuring it out by removing various addons, playing around with different settings etc. - Haven't really succeeding by removing Master Merchant, Awesome Guild Store, ATT, Advanced Filters.
Nothing really seems to fix it, but reloading game helps temporairly and shortens the time of posting an auction.
Any suggestions?
Best,
Matt
