Turns out satd made block processing wait on a 500 ms timer. That severely throttled IBD at about 25 blocks/sec per peer. Fixed in the upcoming 0.7.2/0.8.0, with other fixes bringing 0.8.0 roughly to parity with Core.

satd 0.8.0 will swap out libbitcoinconsensus for libbitcoinkernel. The former is quadratic over inputs, which made txns with many inputs very slow. On testnet4, this could cause the node to fail to sync and enter a restart loop. Default consensus is changing to cpp-shadow (rust authoritative).

satd 0.7.1 is released. I closed out a good chunk of the issue backlog that had built up, adding a number of compatibility and performance improvements. Nothing earth-shattering, but a good upgrade if you're running a previous version.

satd 0.7.0 is, afaik, the first and only Bitcoin implementation to allow full OP_RETURN value pruning/redaction.

Use -pruneopreturn=N (blocks below tip, 288 min) and -pruneopreturnsize=X (default: 4k) and the node will prune the matching OP_RETURN values in block files
