i've built both this PR and the commit it's based on using guix, and the resulting x86_64 bitcoind binaries have the same size. There are subtle differences in the assembly, though:
```bash
objdump -dC --dwarf=follow-links a38603456e9a/bitcoind > a38603456e9a/bitcoind.s
objdump -dC --dwarf=follow-links 4d3da08d1b9d/bitcoind > 4d3da08d1b9d/bitcoind.s
diff -du a38603456e9a/bitcoind.s 4d3da08d1b9d/bitcoind.s > diff
```
```

yes i am a bit divide about this, i understand you don't want to invalidate ACKs last-minute, but on the other hand re-reviewing after a trivial change is super easy, and if we're touching this anyway it's good to make sure it's the best possible documentation

No problem, so I'm gonna address it here.

(https://github.com/bitcoin/bitcoin/pull/31124)
`RegQueryValueExA(HKEY_PERFORMANCE_DATA, ...)` sometimes hangs *bitcoind.exe* on Windows during startup, at least on CI.

We have other sources of entropy to seed randomness with on Windows, so should be alright removing this. Might resurrect if less drastic fix is found.

Hopefully sufficient to fix #30390.

You may want to also modify the "// Dynamic environment data (performance monitoring, ...)" line in `SeedPeriodic()` in random.cpp.

(https://github.com/bitcoin/bitcoin/pull/31117#issuecomment-2426574794)
CI is broken because BIP94 is also active on regtest and this change breaks some functional tests that are not related to the issue. I don't think I need to work on fixing those tests unless I get an indication that people think this is actually interesting to merge.

We are getting some report that the `getblocktemplate` sometimes hangs on a small-ish debian 12 server. I have not been able to reproduce this locally or on a small-ish ubuntu server. Would be great if anyone is interested in tes

Concept ACK as explained in https://github.com/bitcoin/bitcoin/pull/30956#issuecomment-2425157662 - querying all performance counters has a potentially high overhead for the system.

(https://github.com/bitcoin/bitcoin/issues/31116#issuecomment-2426620801)
@qk-santi ok sounds like you have a clear understanding and the behavior is still unexpected. I would check two more things:
- Check your bitcoin.conf for anything that might be affecting mempool policy (rbf, relayfee, whitelist, etc)
- Enable estimate fee logging `bitcoin-cli logging '["estimatefee"]'` and watch debug.log for `[estiamtefee]` messages
