perf: use unordered_set / unordered_map where order isn't relevant

PastaPastaPasta · PastaPastaPasta · commit 319e6ea95073 · 2024-12-18T13:40:38.000-06:00
Did a few quickbench to ensure there isn't some advantage to using the "worse" data structure at small sizes. set: https://quick-bench.com/q/ApPAGguzG2F9AnqM2GkgDAXCzX4 map: https://quick-bench.com/q/PXDdF0HVGpiSmC9Hh5FUSTp0uJU Using unordered_map did show a tiny insertion regression for ~expected sizes on masternodes, but it appears that only 1 access will compensate for that overhead, and each su, some perf results I have are here, show that this std::set usage is causing an imo unacceptably high cpu usage. ``` - 9.18% 0.00% d-mncon dashd [.] CConnman::ThreadOpenMasternodeConnections(CDeterministicMNManager&, CMasternodeMetaMan&, CMasternodeSync&)::{lambda()#▒ - CConnman::ThreadOpenMasternodeConnections(CDeterministicMNManager&, CMasternodeMetaMan&, CMasternodeSync&)::{lambda()#1}::operator()() const ▒ + 6.16% CConnman::IsMasternodeOrDisconnectRequested(CService const&) ▒ - 2.66% std::set<CService, std::less<CService>, std::allocator<CService> >::count(CService const&) const ▒ - std::_Rb_tree<CService, CService, std::_Identity<CService>, std::less<CService>, std::allocator<CService> >::find(CService const&) const ▒ - 2.02% std::_Rb_tree<CService, CService, std::_Identity<CService>, std::less<CService>, std::allocator<CService> >::_M_lower_bound(std::_Rb_tree_node<CService> const▒ + 1.99% std::less<CService>::operator()(CService const&, CService const&) const ▒ + 0.62% std::less<CService>::operator()(CService const&, CService const&) const ```
