16:04:48 <stickies-v> #topic Benchmarking WG Update (l0rinc, andrewtoth)
16:04:53 <l0rinc> #35215 was merged - another 5% validation speedup \:D/
16:04:57 <corebot> https://github.com/bitcoin/bitcoin/issues/35215 | coins: use SipHash-1-3-UJ for CCoinsMap keys by l0rinc · Pull Request #35215 · bitcoin/bitcoin · GitHub
16:05:02 <l0rinc> so now we can use it in #35531
16:05:06 <corebot> https://github.com/bitcoin/bitcoin/issues/35531 | txindex: hash keys and pack positions to reduce disk usage by andrewtoth · Pull Request #35531 · bitcoin/bitcoin · GitHub
16:05:12 <l0rinc> I'm running reindex-chainstate benchmarks to compare master with 29/30/31 to see how they stack up.
16:05:19 <stickies-v> as in 5% faster IBD/reindex?
16:05:25 <l0rinc> yup
16:05:44 <stickies-v> juicy
16:05:48 <l0rinc> in addition to the parallel prevout fetcher
16:05:56 <l0rinc> thanks, that's it from me
16:06:20 <dergoegge> lfg
16:06:21 <Murch[m]> v32 should be quite the speedupz
16:06:41 <l0rinc> especially if we can get the txindex changes in
16:07:10 <l0rinc> Andrew is at a conference
16:07:47 <stickies-v> #topic QML GUI WG Update (johnny9dev)
16:07:58 <johnny9dev> Our preview release is now published to bitcoincore.app. Already got a lot of good feedback on it to work through.
16:08:20 <johnny9dev> I dropped down the glibc the preview builds against for increased compatibility
16:08:39 <johnny9dev> One thing I realized too while testing is that the linux depends build doesnt have opengl and the macos depends uses metal apis so there are performance differences across platforms and it is noticeable. So with that I've been focused on optimizing all of the rendering so any page not visible isn't continuing to draw. I think i got most of the main ones and it will be working much better on linux once the PRs are merged.
16:08:59 <johnny9dev> Then finally I removed gMock from our codebase and will make sure that doesn't get included in our staging branch.
16:09:34 <johnny9dev> that is all
16:09:56 <stickies-v> wdym with dropped down the glibc?
16:10:13 <johnny9dev> built against ubuntu 22.04 instead of 24.04 toolchain
16:10:31 <stickies-v> ooh version downgrade you mean
16:10:32 <johnny9dev> at least one person testing couldnt run the built binary on their version of debian
16:10:38 <johnny9dev> yeah
16:12:03 <stickies-v> #topic QA WG Update (brunoerg)
16:12:17 <brunoerg> hi, no update this week
