> 1. Support high-concurrency and use less memory (Go v.s. Java)

In the context of Go vs Java this is a kind of weird unsubstantiated claim. For example if you think a garbage collector leads to higher memory use; Go uses a garbage collector, just like Java. There are loads of applications which support high concurrency in Java. Such as Elasticsearch and Apache Kafka.

I's a fact that I also don't know why, maybe not mainly because of GC. Java's high concurrency is not impossible but just requires more efforts to tune the performance

If your knowledge about a thing is not able to explain a "fact" then you should be cautious about propagating that "fact".

[hsluoyz]

The fact is a "true" fact, I'm not saying something which is wrong. This is all I care about. I don't need to know why. I'm not an expert on programming languages or look into compiler source code either. If you think the "fact" is not true, plz just give your opinions and evidences.

If you claim a fact is true, you should be the one providing evidence.
