Lags when running redstone circuits with redstone clockers. Example: When I start the redstone clocker (clocker made out of the comparator) in my circuit
the mobs frezze. But when I stop the clocker the mobs speed up.

We'll need more information to diagnose your issue. Is it just the mobs, or does the whole game become slower? Do you have trouble moving, or turning the camera? Does it only happen when facing the circuits? What does the circuit do?

Yes it affects all the mobs. My camera and movements are Ok. It does lag when not facing the circuit. The circuit sends clocking signals to two command blocks the redstone clocking path is controlled by redstone repeaters. But even after removing the command blocks its the same.

Here is an example of the lag: My circuit is ready and I start the clocker first. The first 5 seconds are fine, but then the mobs are like delaying, and when i break the clocker, the lag stops and the mobs teleport to the position they were suposed to be. I used a comparator as the clocker, I tried it with repeaters too, same results. In 1.8 the circuit does not lag.

I've been noticing this as well on a world that hasn't been corrupted yet. It only seems to lag if the clock is connected to a mechanism. It will lag much quicker if that mechanism is also budded.

Actually, updating to JRE 1.8 Update 66 seems to have resolved this for me.

Java notified me that an update is available, but i couldnt download it due to an error. I will try to download it manually, and I will comment it here. Right now I cant.

While it may be related I don't think its actually a duplicate since this issue doesn't require mobs. The clock lag can be seen in Peaceful mode with a minecart.

Wow you're right I tested on peaceful mode and it really lags a lot, like you said.

I am having the same issue in snapshot 16w04a on my server. When any kind of redstone is activated, I get massive server lag, and when the redstone is deactivated, the lag goes away.

Is MC-94438 really now the collection thread for anything regarding lag?
I'm not sure if this is a good idea.
As for this bugpost, this seems rather like a duplicate of MC-81098 ?
I will make a note in the server-lag bugpost regarding that.

Relinked.
