Just cross-posting this here so you can see it better (hope it helps): GTNewHorizons/GT-New-Horizons-Modpack#2261

See a copy of the issue below:

Which modpack version are you using?

2.0.2.0

If in multiplayer; On which server does this happen?

--

What did you try to do, and what did you expect to happen?

I'm testing GT++ multiblocks, and find out this:

1. maceration stack processes ores uncorrectly. According to description, in IV in should produse 8*5 items\operation, means 40\operation, but in realty it process 1 item\operation

2. Industrial sifter
   Works fine, but slow - 1 item\operation too, don't think profit with "more gems" cover it.

3. Industrial centrifuge:
   Can't turn in on, nuff said.

4. Industrial coke oven
   Works, but insanely slow, pyrolisite do the trick much more speedy.
   And, coke coal recipy for example:
   Pyrolisite: 16 coal -> 16 coke in 32 seconds
   InduCokeOven: 8 coal -> 5 coke in 15 seconds
   Eats more energy@Less efficient@Produse less in some time@req steam

5. Industrial material press
   Dunno what this multiblocks suppose to do, can't start it with compressor and forming press recipes.

6. Industrial electrolyser
   Works fine, but process 1 item\operation.

7. Wire facrory
   Works fine, but still - 1 item\operation.

can't test another multiblocks for now, sorry.

Don't think we need "Large multiblock little faster than singleblock machine". I thinked GT++ was added as a replacement for arrays filled with machines, but...

I personally think the sifter is balanced, but maybe you could change it to take in 8/16/32/64 Items at IV/LuV/ZPM/UV, with HV/EV/IV/LuV speed. (or similar)
Ideas for the other Multiblocks:
Change it to take in 1 Amp for every 1/2/4/8/16/32/64 (MV/HV/EV/IV/LuV/ZPM/UV), which can be configured by a circuit (f.e. Cirq 1 = 1A = 16Items per operation at LuV, with LuV+X%speed, Cirq 4 = 4A = 64Items per operation at LuV, with LuV+X%speed)
EDIT: Or 3 x CirqConfigurance x Amp/VoltageTier for VoltageTier+CriqConfigurance x item, but you need to imput 1/2 (uprounded) of the ammount of machines at the desired voltage level into the controller.
(f.e. Cirq 1 = 0.5A = 7Items/Operation at LuV(6), Cirq 4 = 2A = 10 Items at LuV(6), Cirq 24 = 12A = 30Items at LuV(6))

I think this one is more or less fixed.

Yep. Fixed in 1.7.0.
