   The chat requests are going from Overlord to the workers. Surprising that it's causing Overlord CPU to become high. When you see spike in Overlord CPU usage, can you check through thread dumps where are Overlord threads spending their time? Maybe it is something else. 
   
   We have also seen segment allocation cause significant overhead at that scale. This overhead can be reduced by enabling batch segment allocation. `druid.indexer.tasklock.batchSegmentAllocation` needs to be set to `true` on Overlord.
