> Why is this so much slower? Just a side note: Go test supports benchmarking (https://dave.cheney.net/2013/06/30/how-to-write-benchmarks-in-go https://dave.cheney.net/2013/06/30/how-to-write-benchmarks-i...) which gives you few useful tools such as `b.ReportAllocs()` and `go test -bench . -cpuprofile cpu.out -memprofile men.out`. These tools can give you far better information than just the execution time of a test case.
