[MCPE-89260] Repeating redstone causes world lag

Since 1.16 has come out, there has been lag attributed to a lot of things. My observation has to do with lag with repeating redstone. I have observed this in both a single player world, and on a server running BDS. My specific example has me using a portal ticking gold farm. Prior to 1.16 you could run 4 portals on a fast clock, and tick them in rapid succession to spawn a lot of pigmen in quickly. Now, you can use this same clock to tick 1 portal without lag, but increasing to more than 1 will slow the redstone down to a slow pace. Ive had to move to a 4 tick delay for 4 portals for them to not lag. Other designs I have seen are doing this as well, and reports of running any sort of repeating redstone alongside trident killers is doing this as well.

So annoying this bug! I have this issue on my single player, a Dedicated Server, general multiplayer, and my friends have it on their realms. It just stop gold farms from being as efficient as they could be!

Being an player that prefers to automate almost all things in minecraft this has severely damaged most all of my bases and contraptions, the lag gets so bad that i drop to a frame rate that belongs back in 1800's, no lie my flick book animations have a better frame rate, my xbox fan kicks in so hard when the redstone is in my load area and splitscreen is no longer viable with this bug still around.

I would much appreciate a fix to this as soon as humanly possible.

Thanks for reading my rant.

Dependning on how you're handling the XP output and on/off toggling, it could be XP_orb and mob collisions rather than repeating redstone that is causing lag in high-output farms. For example, if one player leaves the farm running and walks away or logs off in it.
