Productivity display shows 50% efficiency even though inputs and outputs match?

[Satori]

Hey all,

Confused about something, and it's bothering my OCD/inner efficiency nut, I checked the input/output on my buildings, for example a smelter, and it's taking in plenty of copper and is connected to 2 constructors. 30 copper in, 30 ingots out.

Yet the productivity display shows an efficiency of 50%! What gives? What am I missing? Is it the speed of the conveyor belt or something?

How do I get efficiency to 100%?

Have you just recently started the smelter? If that is the case then it will take some time until it will be showing 100%

What are the resource numbers inside the building? it could be the the input is not getting enough to be fully active or the output is full and it can't make more

[Satori]

Now it's showing 40% efficiency. This is very confusing. It's got 100 copper ore in it and it's pumping out to 2 constructors. It's been running for like a half hour.

What is showing 50% the smelter or constructors?

Are you sure that all the production is being used? Because if the output gets clogged then it won't produce anything anymore when the maximum stack size of the produced item is reached. That in return is lowering efficiency on the display.

What's the purity of the node?

That is why you aren't at 100%, you should not have 100 ore sitting in it. Is being fed faster than it can make the ingots.

That's not how efficiency works in this game though. Efficiency only calculates based on the percentage of time that it's running. Over supplying a machine will still result in 100% efficiency because the machine is running 100% of the time (assuming no backed up outputs).

How many copper ingots are in the output?

[Satori]

There are 0 copper ingots in the output, they're all being sucked out of the Smelter. That's why I'm confused haha. I'm on experimental so maybe something is wonky?

I have found a similar problem with efficiency in other machines like an assembler. Lets say the machine needs 10 parts. When 10 parts show up in machine inventory the machine removes the parts but will not begin production until another 10 parts show up in inventory. When supply is fast you don't notice because supply in inventory always exceeds the 10 parts. But if supply is slow it takes time to supply the initial 10 and then the machine waits on production until the next 10 are supplied in inventory. In the long run this may no make any difference because the supply of parts really is limited. But if you are watching the display you will easily notice the delay in production and the efficiency will not be 100 percent even through the machine is supplying the 10 pars in the required time. If the production is slow enough the next 10 parts will get supplied during the production. But because the machine will wait for another 10 parts to show up before it starts thus about doubling the time time and so the efficiently will show as 50 % instead of 100 % which it really should be achieving. Its a little confusing and you generally won't notice it unless you get the right conditions and are watching closely. This can be a real pain when you are waiting for production of 4000 parts at one part per minute so it takes twice as long to get it done.
