I am currently an operator on a Minecraft server, and one of the problems that we run into is people using Redstone and causing lag, especially when they build loops, or anything that pulses. Now, I've heard that the chief cause of Redstone lag is actually the lighting updates that occur. I realize that all lighting calculations are done client side, but that just means that the lag is client side. The reason the loops produce so much lag is because of the continuous information being sent to and from the server, and the continuous lighting updates that must be processed by the client. Is there any sustenance to this theory? If so, can you source any info please, I have a few people I need to convince of this theory. If not, could you help explain why the redstone causes the lag?
Also, does it make a difference in lag if you have a redstone system that is off vs a redstone system that is permanently on, but not pulsating?
Thank you in advance!
