There are alot more stuff that OpenJDK does not have. Try running it on ARM for example, it's like 4 times as slow, unusable.

There's a full C1+C2 port to ARMv8 here:

http://openjdk.java.net/projects/aarch64-port/

Are you sure it's 4 times as slow? I'd be surprised if that is the case, but don't have the hardware to check.

I'll make a benchmark when there is some feature that the free forever Java SE JDK 8u181 does not have that I need, until then I'm only using 8u181 (or anything better that comes after that and before Jan 2019)

I'd be surprised if the exact same codebase (as of Java 11) was 4x slower just because it's called OpenJDK.

Yes, in this case it is not the exact same codebase. There are actually a number of ARM backends in OpenJDK. If i recall there is an A ARMv5/6 one from the community and Oracle open sourced one for the same or for v7. And then the modern AArch64 one.
