I'm working on some logic, using fill clocks to drive my command blocks.
I usually end up having to extend my circuit, and rather than adjust the fill clock command, I usually just put in some redstone dust.
My question is, does this add more load than extending the fill clock?
I know that when making a fill clock, you must use a solid block in place of the redstone block, so that lighting updates are not triggered.
Does redstone dust trigger a lighting update when it's switched?
Wiki kinda made a mistake: by the "C changes from 0 to 1 or 1 to 0" it means you can design it to be edge up trigger or edge down trigger not both. If you look at the design it self you will see that the first split from input C only send pulse transitions when you change it from 0 to 1 and when you change it from 1 to 0 it's doing nothing. So this work's alright just a little miss understanding, if you need so here the edge down design I built(just added not before the C):
I fixed this in wiki so this should be fine now.
Btw you can design both edge up and down trigger, you need to send pulse(circled in black) each time the clock is changing. Do it your self as a challenge ☺
Version 1.5 included a whole load of new redstone mechanics, and as such the underlying redstone system changed a fair bit - breaking some devices.
What you have posted is an example. There are plenty of other clocks you can make that work in newer versions, try one of those.

Yes it does
This article goes into quite a lot of depth on the matter but the main point is that while redstone dust does not trigger lighting updates, it does trigger redstone propagation updates, which are just as bad! Wherever possible, redstone dust should be eliminated from clock circuitry, or any circuits that are running very frequently. Use fill strips instead to power all your command blocks.
