I noticed that the Dissolution and Crystallization Chamber both implement TileComponentUpgrade, and so can be sped up significantly, while the Washer, which sits between them, does not, and so consistently bottlenecks. I understand that the system is meant to time consuming, but I was surprised by the inconsistency, so wanted to bring it up.

I'm going to assimilate this into #2032.

It's probably due to the fact that only machines with a "number of ticks to operate" mechanic currently support upgrades, not the "amount done per tick" machines. I'll try and get more machines supporting upgrades with the new upgrade system in v8.
