That's not necessarily a bad thing for writing web services. I used to spend a fair bit of time tuning JVM to achieve acceptable tail latencies for Java services, not to mention once in a while, they would need to be tuned again... Not so with Go.

The Go GC and the JVM GCs are built within very, very different constraints.

Since most short-lived allocations in Go are stack-allocated, the cost of adding a read-barrier and branching on every heap access is more expensive than the potential gain from bump-pointer allocation.
