Upon drinking a potion this shouldn't apply any rules, isn't it?
Do you use EVENT_INVENTORY_SINGLE_SLOT_UPDATE?
You should really register a filter on the event then so only the update reason REGISTER_FILTER_INVENTORY_UPDATE_REASON -> INVENTORY_UPDATE_REASON_DEFAULT is considered in the C code and passed to your event's callback function!
And add a filter for REGISTER_FILTER_UNIT_TAG, "player" so only your player updates to this event apply and not the game inventory single slot stuff like "if you repair an item" or "if you charge a weapon".

+you can check for IsNewItem == truie for most of the rules, maybe, which will speed up as well.
+this event is even called if you upgrade your horses bags. But this new bag space won't affect your rules as no items will be. So check for the stable_scene active and do nothing then if the event is called during this scene is active
+check if you are gertting arrested which will scan your bags with the event too, or if you loose your stolen items it will be
+check if the itemtype of the item the event checks got an itemtype, if you got rules with an itemType relevance


Edit:
+I forgot about other addons triggering these event really often e.g. Roomba on restacking guild bank items

There might be some difficulties which need you to react differently depending on your rules to check but these improvements should all be "base check" for the event to speed up.

Hey. It'd be great if you were to hook up functions to query the Auto Category addon.

You can see the API on the on the AutoCategory GitHub repository; matching on the assigned category name would be what most interested me.

Thank you for this add-on. It's the most robust inventory manager I've seen so far.

Just a minor request: Is there any way to remove the freezing/lag every time you open up the bank UI?

The delay is quite long (my game freezes for 4-5 seconds). I know other inventory manager add-ons (Inventory Manager and Bank Manager) don't have a delay, or have a very short one.

The only rule I am using is "(materials)" for bag-to-bank and "exclude bank-to-bag" is turned on.

My inventory has ~30 items and bank ~220.

My hardware (if it matters):
R5 1600
GTX 1080

I have 8-10seconds..... but when i disable master merchant,only have 3sec.

oh,btw,i got ur message,i uesd new version at the 1st time
thanks for ur work.

Please disable the "destroy" rules while fetching items from the bank, or possibly just add a facility for me to declare they should not operate at that time.

Turns out if you use roomba to restack lockpicks in the guild bank, which withdraws the two stacks of 25, and that puts you over the limit you configured.... you don't have them to put back in any longer.

When running deconstruction rules, it would be nice to have the addon listen for the "work is finished" event, and then trigger the next action, rather than a fixed delay. That should not overwhelm the backend, but should minimize delays.

Yeah, that should sort it out. It was basically "roomba withdraws over the limit, destroy rule destroys, I regret my life choices".

(Only lockpicks though, so I don't really care.)

Wishlist: support refinement, as well as deconstruction, at crafting stations.

Another wish, either an option to auto-switch to the tabs and process all rules on open, or an indicator on the refinement / deconstruction tab if there are items that would be processed there.

Absolutely! I am very happy you are doing this at all! I'll post things as they pop up, or whatever, but I don't have any expectation you will ... well, heck, I don't expect you to ever have to do them, and certainly not "right now" or anything.

Thank you for doing all this! The addon is great, and I appreciate all your hard work. I'll be super-happy whatever you do.
