While it’s a nice bed time story if you like go, the reality is no, it’s not typical.
Go has a good perf story, but typically rust or c++ would be faster after heavy optimisation; and should be more or less on par with typical applications. This isn’t a critique of go, and shouldn’t surprise anyone.
Typically go also has unexpected optimisation hoops to jump through and problems related to the heavy use of channels (see the well documented answer here: https://stackoverflow.com/questions/47312029/when-should-you...), so you would generally expect it to be slower…
…but, naive implementations are always slower, and really, it’s probably much of a muchness out the box for most day to day uses.
In almost all situations (even python or Java) you can get great performance if you invest time and effort in it.
But idiomatic code typically faster than rust? No, not really.
