Since TWW I noticed significantly longer loading times when switching zones (teleport, hearthstones, dungeon portals etc). So much so, that I logged onto my mage, made an excel spreadsheet and teleportet ~100 times between Stormwind, Valdrakken and Dornogal with different addon combinations and logged the loading times with a stopwatch.

Overall most addons extend loading times by 10 to 100 ms.
BaudBag is more in the range of 2000-3000 ms.

So, while not game breaking, BaudBag takes longer to load (2-3 Seconds per loading screen) between zones, than any other of my addons. Including big ones like Altoholic, WeakAuras, Details, DBM etc. which all only take about 50-100ms.

Do you have any idea why? I'm guessing due to all the changes in TWW BaugBag is far from optimized currently, but I couldn't help but notice the loading times issue.

I'll have to dig a bit deeper which kinds of events are happening when switching zones. From the top of my head I don't remember handling any events that should fire on each loading screen, but it is possible, that blizz is again sending useless bag update messages which cause subsequent refreshes on almost everything.

2-3s is definitely to long for what the addon does.
