Hi @farmhouse ,
Thank you for reporting this. My scale testing for terminator creation has usually testing in the range of 5k-10k terminators, so I haven't hit this myself.
I agree that the single writer shouldn't cause degradation of that severity. There's also some amount of exponential back-off happening, but that should cap at a reasonable level.
I'll have to run some tests and see what I can find. I created an issue to try and make sure we don't lose track of this, as I likely won't be able to get to the testing immediately: Terminator creation seems to slow exponentially as the number of terminators rises from 10k to 20k to 40k · Issue #3318 · openziti/ziti · GitHub
