The previous code was not accounting accurately for the time spent generating test cases. In the benchmark output below the difference between 100 address per peer suite is huge: BenchmarkInMemoryPeerstore/SetAddrs-100Addrs-InMem-16 10000 190198 ns/op vs BenchmarkInMemoryPeerstore/SetAddrs-100-16 10000 42710 ns/op old benchmark: ``` goos: linux goarch: amd64 pkg: github.com/libp2p/go-libp2p/p2p/host/peerstore/pstoremem cpu: AMD Ryzen 7 7840U w/ Radeon 780M Graphics BenchmarkInMemoryPeerstore BenchmarkInMemoryPeerstore/AddAddrs-1Addrs-InMem BenchmarkInMemoryPeerstore/AddAddrs-1Addrs-InMem-16 10000 4158 ns/op BenchmarkInMemoryPeerstore/AddAddrs-10Addrs-InMem BenchmarkInMemoryPeerstore/AddAddrs-10Addrs-InMem-16 10000 26364 ns/op BenchmarkInMemoryPeerstore/AddAddrs-100Addrs-InMem BenchmarkInMemoryPeerstore/AddAddrs-100Addrs-InMem-16 10000 197692 ns/op BenchmarkInMemoryPeerstore/AddGetAndClearAddrs-1Addrs-InMem BenchmarkInMemoryPeerstore/AddGetAndClearAddrs-1Addrs-InMem-16 10000 3692 ns/op BenchmarkInMemoryPeerstore/AddGetAndClearAddrs-10Addrs-InMem BenchmarkInMemoryPeerstore/AddGetAndClearAddrs-10Addrs-InMem-16 10000 23182 ns/op BenchmarkInMemoryPeerstore/AddGetAndClearAddrs-100Addrs-InMem BenchmarkInMemoryPeerstore/AddGetAndClearAddrs-100Addrs-InMem-16 10000 202959 ns/op BenchmarkInMemoryPeerstore/Get1000PeersWithAddrs-1Addrs-InMem BenchmarkInMemoryPeerstore/Get1000PeersWithAddrs-1Addrs-InMem-16 10000 25348 ns/op BenchmarkInMemoryPeerstore/Get1000PeersWithAddrs-10Addrs-InMem BenchmarkInMemoryPeerstore/Get1000PeersWithAddrs-10Addrs-InMem-16 10000 20133 ns/op BenchmarkInMemoryPeerstore/Get1000PeersWithAddrs-100Addrs-InMem BenchmarkInMemoryPeerstore/Get1000PeersWithAddrs-100Addrs-InMem-16 10000 17525 ns/op BenchmarkInMemoryPeerstore/GetAddrs-1Addrs-InMem BenchmarkInMemoryPeerstore/GetAddrs-1Addrs-InMem-16 10000 163.5 ns/op BenchmarkInMemoryPeerstore/GetAddrs-10Addrs-InMem BenchmarkInMemoryPeerstore/GetAddrs-10Addrs-InMem-16 10000 203.9 ns/op BenchmarkInMemoryPeerstore/GetAddrs-100Addrs-InMem BenchmarkInMemoryPeerstore/GetAddrs-100Addrs-InMem-16 10000 1696 ns/op BenchmarkInMemoryPeerstore/SetAddrs-1Addrs-InMem BenchmarkInMemoryPeerstore/SetAddrs-1Addrs-InMem-16 10000 3431 ns/op BenchmarkInMemoryPeerstore/SetAddrs-10Addrs-InMem BenchmarkInMemoryPeerstore/SetAddrs-10Addrs-InMem-16 10000 21599 ns/op BenchmarkInMemoryPeerstore/SetAddrs-100Addrs-InMem BenchmarkInMemoryPeerstore/SetAddrs-100Addrs-InMem-16 10000 190198 ns/op ``` new benchmark: ``` goos: linux goarch: amd64 pkg: github.com/libp2p/go-libp2p/p2p/host/peerstore/pstoremem cpu: AMD Ryzen 7 7840U w/ Radeon 780M Graphics BenchmarkInMemoryPeerstore BenchmarkInMemoryPeerstore/AddAddrs-1 BenchmarkInMemoryPeerstore/AddAddrs-1-16 10000 899.2 ns/op BenchmarkInMemoryPeerstore/GetAddrs-1 BenchmarkInMemoryPeerstore/GetAddrs-1-16 10000 914.9 ns/op BenchmarkInMemoryPeerstore/GetAndClearAddrs-1 BenchmarkInMemoryPeerstore/GetAndClearAddrs-1-16 10000 699.5 ns/op BenchmarkInMemoryPeerstore/PeersWithAddrs-1 BenchmarkInMemoryPeerstore/PeersWithAddrs-1-16 10000 112298 ns/op BenchmarkInMemoryPeerstore/SetAddrs-1 BenchmarkInMemoryPeerstore/SetAddrs-1-16 10000 764.7 ns/op BenchmarkInMemoryPeerstore/AddAddrs-10 BenchmarkInMemoryPeerstore/AddAddrs-10-16 10000 4682 ns/op BenchmarkInMemoryPeerstore/GetAddrs-10 BenchmarkInMemoryPeerstore/GetAddrs-10-16 10000 5310 ns/op BenchmarkInMemoryPeerstore/GetAndClearAddrs-10 BenchmarkInMemoryPeerstore/GetAndClearAddrs-10-16 10000 4147 ns/op BenchmarkInMemoryPeerstore/PeersWithAddrs-10 BenchmarkInMemoryPeerstore/PeersWithAddrs-10-16 10000 93408 ns/op BenchmarkInMemoryPeerstore/SetAddrs-10 BenchmarkInMemoryPeerstore/SetAddrs-10-16 10000 4412 ns/op BenchmarkInMemoryPeerstore/AddAddrs-100 BenchmarkInMemoryPeerstore/AddAddrs-100-16 10000 40847 ns/op BenchmarkInMemoryPeerstore/GetAddrs-100 BenchmarkInMemoryPeerstore/GetAddrs-100-16 10000 40197 ns/op BenchmarkInMemoryPeerstore/GetAndClearAddrs-100 BenchmarkInMemoryPeerstore/GetAndClearAddrs-100-16 10000 37848 ns/op BenchmarkInMemoryPeerstore/PeersWithAddrs-100 BenchmarkInMemoryPeerstore/PeersWithAddrs-100-16 10000 111613 ns/op BenchmarkInMemoryPeerstore/SetAddrs-100 BenchmarkInMemoryPeerstore/SetAddrs-100-16 10000 42710 ns/op ```
