07:01:52 <M0xffc[m]> For someone who is new (and hasn't run profiling on Monero), if you want to sum it up, which part of the Monero is the bottleneck (performance-wise)? 
07:03:19 <moneromoooo> Transaction/signature verification.
07:03:43 <moneromoooo> If you run without fast sync, probably PoW.
07:04:34 <moneromoooo> Fast sync only applies to historical blocks. Do you mean that or just keeping ahead as blocks are found ?
07:04:57 <M0xffc[m]> The bottleneck is the computation itself? or there are opportunities to improve it implementation wise?
07:07:32 <M0xffc[m]> The reason why I am asking is that I was reading this paper today, https://www.cs.uic.edu/~jakob/papers/sosp17_techrep_draft.pdf Stuff like this (this one does not apply to monero directly), can improve software implementation.
07:12:22 <M0xffc[m]> Or this one: https://arxiv.org/pdf/1905.01135.pdf this might not apply directly too. 
11:49:13 <woodser[m]> I think I may have found a problem in wallet2, where if the wallet is first created in-memory, then it will fail to save to disk, given this logic: https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.cpp#L6238
12:00:42 <woodser[m]> opened an issue if anyone can fix: https://github.com/monero-project/monero/issues/8932
