Does Redstone Lag?

[trexation 14]

Many people have told me that "Redstone lags!" "Redstone sends my computer strait to the nether!" "Destroy all the red ore before it is too late!" "OMG not redstone anything but that!!!"

 

I have never had an issue with lag caused by restone and decided to see just how much redstone it would take to lag me. so I built this. Thank goodness for single player worldedit!

And all this caused me to do was rarely dip into the high 40s fps, then I tested it with shaders!

Normally I get about 20-22 fps when most of the chunks nearby are loaded, here is an example world with no redstone and me using shaders.

And so, after having a base mark to go off of, I swapped over to the redstone world, and got an average of 14-16 fps, so some lag IS present, but I would like to argue that the sunshafts coming between all the builds is causing the lag and not the redstone.

and so to test my theory that it is just sunshafts I decided to turn all the restone into string, all the repeaters into cakes, and all the pistons into cobble, after doing this I got very similar amounts of lag, high 40s every once and a while, and I got about 18 fps with shaders on.

 

Conclusion: Redstone does lag slightly, but it is rather minimal if built correctly. so, what can I do  to prevent redstone lag? The worst lag creators are in a list below in no specific order.

- Large amounts of dropped items, arrows

- Redstone clocks (worst are 1 tick clocks)

- Lots of mobs (blazes are the worst! Remember this event staff!)

- Lots of players

- Fast moving pistons (ie active shifting floors)

- HOPPERS! (notably putting blocks on top of hoppers make little difference in the lag, just fyi

- Signs, banners

- Leaves, glass, portals, enchant tables

 

I hope this helps prove to city leaders that redstone traps are possible inside a city without causing lots of lag. Looking for someone to install redstone traps in your city, town, or house today? Please msg me on the forums or in mc for more details (here is the rp post about that https://www.lordofthecraft.net/topic/129040-daans-redstone-building-and-instaling-redstone-systems-since-vailor/ ).

 

 

This build is exactly-

 

48384 Pistons (Sticky)

67200 Redstone torches

18816 Redstone

16128 Repeaters

A lot of Stone

 

Want to download the world? Sure! here is the link https://www.dropbox.com/s/8qf9djtwcny3upl/Lag%20Test.zip?dl=0

just unzip it and and put it in your saves folder. to get to your saves folder hit [windows key] and [r] at the same time then a box will apear. Type into the box (that says run) %appdata% go to the folder that says .minecraft and then open saves.

 

Please post in the coments what fps you got in my redstone map.

Nation leaders are justifiably weary of redstone devices in cities as the redstone lamps in Petrus made that city nearly unplayable for most.

 

I remember nathanbarnett removing the lamps and replacing them with glowstone to reduce the lag.

Was it timer based, that would be the cause of the lag. also daylight sensors prob are not good for lag.
