10:31 <laanwj> and it makes sense, bitcoind is optimized for various POSIX platforms, not windows, which is different in many aspects; for example leveldb, doesn't even really support windows by itself; the win32 API backend it uses is something i worked on. also the P2P networking doesn't use any i/o polling primitives optimized for windows. Disk i/o is also slower on a lot of windows machines due to windows defender etc getting in the way. To get any level of 10:31 <laanwj> performance there would need a lot of work. Still, it shouldn't be that slow... 10:34 <laanwj> compiling with MSVC instead of mingw also used to be an improvement in speed, but this was 2013, no idea about now, and we can't use that in deterministic builds anyhow 10:36 <hebasto> MSVC builds lack HW-acceleration for SHA256 -- https://github.com/bitcoin/bitcoin/pull/24773 10:36 <darosior> He did mention MSVC vs mingw and i quickly got out of my depth. :) 10:36 <darosior> What do we use for release builds? 10:36 <hebasto> mingw 10:36 <laanwj> mingw, because that's the only thing we can use in side guix 10:36 <laanwj> well we could use clang that would be something to investigate, many seem to prefer that for windows nowadays 10:37 <hebasto> right
