This glitch with the insane redstone lag was apparently fixed on one of the last snapshots, but it is still present in the final release. I am playing in my Minecraft Brawl PvP map, which worked perfectly fine in 1.8.9. Running it in 1.9 shows a MAJOR difference in performance.

Here is the launcher log from 1.9:

As you can see from this log, I get a warning stating that the internal server "Can't keep up!" and that it skips 592 ticks. In the game itself, everything is acting like I'm connected to a very laggy server(network lag, not fps lag). I would like to know why this is happening, and when it will be fixed. Also, before you go telling me to use the new redstone stuff, I have tried that too, and the same thing happens like if I have the /fill clocks. Also, here are my computer specifications if you need them:

Intel i5 @ 1.7Ghz with Turbo Boost up to 2.4Ghz

6GB DDR3 RAM(2GB associated to Minecraft)

Intel HD Graphics 4400

Windows 10 Home(version 10.0.10586)

Ok, its been over two days now, and I have not recieved any support or help from anyone. I would like to know WHY this is happening and how I can fix it.

Over two weeks, and no one has given me any solutions or help. Makes me think that this forum doesn't really care about helping people with game issues that they have. Also, a few servers that I play on are having the same issues as me when running my map, or any other map with redstone clocks in this instance. And they don't know why this is happening either.

I don't know why everyone is ignoring this, but I just need a solution to this issue.

This is most likely due to your cpu being below the recommended requirements. I would recommend getting a cpu that at least has 2.6Ghz.

So basically, I need to have a high-end Intel I7 processor with 8 cores and 2.6Ghz? An intel I5 at 2.4Ghz with 4 cores isnt enough to handle common redstone clocks now? And I would also like to know why this lag issue just mysteriously happens when I update to 1.9, and not when I am running 1.8.9.

Servers that run with high-end specifications are also lagging like crazy.

Its also good to know that the majority of people that play the game use lower-end computers, and Mojang raising the minimum specifications to run maps with simple redstone clocks is just a bad move.

This is a user to user forum. If no one has chimed in maybe nobody knows the answer.

When you figure it out, you can let other users know right here.

Meanwhile, how you post has a major impact on what kind of help you get. If it was fixed in a snapshot, which one? Maybe you should file a bug.

That "fix" from the snapshot didn't work. I still get the same performance that I got before the "fix" was released, insane redstone lag. And if servers with high-end specifications are experiencing the same issue while running games with redstone clocks, then there is an issue with the game.

Recommended meaning best to have. Also there are many other cpus that aren't "high end" that have a 2.6Ghz cpu. Of course 1.9 is going to be laggy since it is a new update and has changed the way redstone now works. It could have also been more laggy when compared to previous versions if you had used optifine in the previous versions.

But still, why release an update that causes extreme lag and issues to Computers that could run game with no issues before? Why even re-do the redstone system completely to the point of it lagging on lower-end PCs? The redstone mechanics in 1.8.9 and lower were completely fine, all they should have done was add the new blocks without re-doing the system.
