Other things you want to watch out for are pistons as they become transparent when extended in this case you may want to saturate both sides of the piston where applicable.
Actually, pistons are transparent in both retracted and extended states. (On the 360 version anyway) I wouldn't think they would give you too much of a problem.
Thanks alot for the information! I will definitly try this out in my world because I'm trying to do a redstone contraption and when somebody joins I just have so many lag spikes and it irritates me! But bravo for finding that out.

I am a angel, I shall disperse all demons from you.
I may be a angel, but that doesn't mean I have evil in me.
I'm not like any other angels, I posses all powers you can imagine.

Ahh yes thanks for that, I wasn't sure if they were transparent all the time or not.
Would it be worse than signs and would it be a good idea to place redstone on pumkins for wiring?
It's about the same, in recent Etho video he said how his storage room with a lot of item frames were causing lag, IIRC he had about 130ish. Pumpkins will work just as well as the glowstone they give off light and they have the ability to contain the light from the redstone items. Just make sure to encase the repeaters and torches, having one on the bottom won't be sufficient.
For those asking/wondering:
It is much better to use glowstone or pumpkins rather than torches because torches give off particles and have a flicker effect that causes BLLUs in and of itself. This in turn can cause lag as the game has to calculate for every torch.
Besides glowstone and pumpkins give off more light so you theoretically need fewer of them.
does the number of chunk updates decrease when the area is lit up by glowstone?
The number of updates is reduced by the number of light-level updates the glowstone eliminates. It does not account for other updates caused by particles, mobs (and other entities), flowing water/lava, etc.
So the answer is Yes.
the flicker effect happens with any placed light source.
Sorry it doesnt. Only torches. Glowstone and pumpkins give off consistant light.
EDIT - Derp. You are right. The flicker happens with other light sources as well. My apologies.
Light levels! I never would have thought! I've been trying to make a music player with a 25 note block speaker and a piston memory storage device for days and the problem I've had with all of them is severe lag. My redstone circuits are going to look a lot prettier from now on. XD

I'm just recording the construction process of my Ultimate, minimum redstone Mob Grinder (And having way too much fun with the video editor!)
Just tested the glowstone technique and wow, it works really well! I thought a good place to test it would be my 16-bit calculator, as it is very complex and used to generate a lot of lag when converting large answers from binary to decimal due to heavy use of ripple-carry type adders.
I still notice a small drop in frames but the improvement is still massive.
Nice topic. Good research from Rush. Almost needs to be stickied.
It seems like 4J could get considerable performance improvement if they deliberately made Redstone torches and Repeaters not be light sources (like Redstone dust itself), and thus would prevent triggering BBLUs on their own.
Now that we have actual Redstone Lanterns, I can't imagine anybody is using a Redstone torch as some kind of switchable light source.
A small deviation from PC would be worth it to help keep the 360 version humming along.
However, if at all possible, could you plz try to find out why using many hoppers in conjunction with trapped double chests seems to lag my Xbox 360 minecraft right down to slower than a crawl, as I'm completely stumped.
Lots of hoppers cause lag. There is no way around it. They are always looking for stuff to pick up on top and take up bandwidth by doing so. You can reduce the lag slightly by putting droppers on top of the hoppers that do not need to pick up stuff from the top. Add to that the fact that chunks do not unload on old gen and you can max out your processor in no time. Large sorting systems are a no-no on 360 unless you want to lag the crap out of your game. The hardware just isn't powerful enough to perform all the calculations at 20 ticks per second.

EDIT: sorry nevermind. its the pc version
Nothing worth learning is easy!

I hadn't read this thread, so I'm actually glad you bumped it. That's some interesting info on light-update-induced lag.

Since we are talking about the Console version... I assume you mean 4J Studios... not Mojang?
It makes sense now that you mention it--the calculations needed to do lighting updates can be quite "painful" for the computer.

Thank you, that was very helpful ☺

it would be nice if there was a gamerule "/gamerule doRedstoneEmitLight false" or something but unfortunately that is not a thing
