Playing a modpack with both TSS and Modern Industrialization in the pack. When the server started having TPS issues it was discovered several players had a setup that was generating huge TPS lag.

A TSS Inventory Cable Connector connected to MI Item Pipes (for the purpose of bulk extracting and inserting) items in and out of the system (ala a AE2 interface) appears to be doing calculations every tick against the entire TSS network. This scaled up starts generating a significant TPS lag.

This setup might not be needed if there was a faster way to import into a TSS network than the basic inventory hopper, perhaps an advanced version that moves a stack at a time?
