It starts slowing down before that (around block 790k), but it gets real nasty after it (840k+ on 29.x). I'm not 100% convinced that it is only secp - am natively compiling bench right now for 26, 27, 28, 29 and 30 - see if I can spot a regression

Mh, the default assumevalid block was 886'157 in v29.0.

Oh, you know what? I have a theory. There was a period of time when people started to churn UTXOs to sift for rare sats. Perhaps the slowdown coincides with a big increase of old UTXOs being spent?

Looking at a UTXO Age band chart, the number of coins held in UTXOs older than one year peaked in November 2023. I haven’t found data on UTXO counts itself yet.

This is plausible, as well as massive consolidation of near-dust. The first ones I found that were slow going were blocks that were heavy on consolidation txs.
