General Description
I used the following command inside a command block in repeat mode:
summon minecraft:axolotl ~2 ~ ~ {Age: -100000,Variant: -1}
When I placed a redstone block next to the command block I noticed aslowdown in the world and looking at the graphs in the F3 menu, I saw a massive spike in the TPS. When the redstone block was removed, I noticed the graph 'catching up' and afterwards everything returned to normal. Screenshots and a screen recording of this occurrence are attached*.Steps to reproduce
- Place a command block in the world
- Set the command block to repeat mode and insert the following command:
- summon minecraft:axolotl ~2 ~ ~ {Age: -100000,Variant: -1
}
3. Activate the command block

I used the following command inside a command block in repeat mode:
{{summon minecraft:axolotl ~2 ~ ~
{Age: -100000,Variant: -1}}}
When I placed a redstone block next to the command block I noticed a slowdown in the world and looking at the graphs in the F3 menu, I saw a massive spike in the TPS. When the redstone block was removed, I noticed the graph 'catching up' and afterwards everything returned to normal. Screenshots and a screen recording of this occurrence are attached*.
I later changed the command to make the NBT valid again:
summon minecraft:axolotl ~2 ~ ~ {Age: -100000,Variant: 2}
This worked as expected: after placing the redstone block, a lot of Axolotls spawned, all of variant 2, and no lag was to be observed in both the world en the TPS graph.
Steps to reproduce
- Place a command block in the world
- Set the command block to repeat mode and insert the following command:
- {{summon minecraft:axolotl ~2 ~ ~ {Age: -100000,Variant: -1}

I'm sorry for editing the post so much, the formatting kept breaking for some reason
That's very interesting... I see you are in a superflat world where I was in an normal world and I was wondering if that made a difference. So I tried the command again, also in a superflat world this time and I seem to get massive amounts of lag there as well, way more than you seem to be getting
I ran a performance metrics debug test while this lag spike occurred and I've attached the resulting zip file 2021-06-27_22_40_01-CmdDed-1_17.zip
