How to reproduce the performance issue

Create a large array of subnetworks and connect them only with quartz.

I don't know the exact amount, but eventually the TPS will start dropping considerably.

Additional details

I am attempting to create a massive storage area for my world, which includes lots of Quartz cables/cables in close proximity/lot of storage drives.

Somehow, when I isolated cables between individual parts of the setup using quartz cables, AE took it as a subnetwork as the power could still flow through, creating thousands of subnetworks in the process.

My TPS dropped massively down to 2, and sparks shows something about power.

However when I swapped the Quartz with toggle bus, and removed energy cells, everything now works just fine. This leads me to think that sub-networks are somewhere dragging down the TPS with calculating power.
