💬 andrewtoth commented on pull request "validation: fetch block inputs on parallel threads >10% faster IBD":
(https://github.com/bitcoin/bitcoin/pull/31132#issuecomment-3361944949)
Updated the input fetcher significantly:
- uses counting_semaphores to synchronize threads instead of mutex + condvar.
- stores tx + vin indexes in global vector instead of copying the COutPoints. The COutPoints are read from a global CBlock pointer.
- The fetch queue counter is an atomic int instead of a mutex guarded int.

💬 sipa commented on pull request "Cluster mempool implementation":
(https://github.com/bitcoin/bitcoin/pull/28676#issuecomment-3362136518)
@sdaftuar and I ran a simulation, replaying most of 2023, and grabbing a `getblocktemplate` just before every real block, in a node with `-bytespersigop=0`. For each three numbers were computed:
* (a) the fees gathered by the `getblocktemplate` template itself.
* (b) the fees found using the same mempool, using a dynamic programming algorithm that finds the optimal template restricted to just cluster prefixes at chunk boundaries.
* (c) a conservative overestimate, computed by eagerly filling
