Issue type:

• 🐌 Performance issue

Short description:

I have an exporter with a variable card that points to an inventory reader with all items I need to be exported to an Obsidian Furnace from the Iron Furnaces mod. When I put the card in the Export Items position the lag from the furnace spikes up to around to about
115,671 us/t. Without the variable card, it goes down to ~ 220 us/t.

I changed the variable to one programmed to a list of items instead of the inventory reader and I had the same exact issue.

Steps to reproduce the problem:

1. ... Put items to burn in Obsidian Furnace from Iron Furnaces - they burn fast!
2. Put variable card pointing at inventory reader with 11 items, lag spikes and the furnace stutters while cooking
   3- Remove variable card, open furnace, things are lightning fast again
   4- Put variable card with same 11 items programed in programmer using list - furnace goes back to stuttering and lag spikes again
   5- Remove variable card, everything works well

Thanks!
Could you share a screenshot of your setup?
Because I can't really see the connection of the profiling log and your description.

It's quite simple. I already removed it because of the lag so I just recreated it the way I had it before.

Let me know if you are looking for something different.

BTW, the same happened with a Pulverizer from Thermal Series. Exact same setup
