I published some benchmarks of OpenJDK on Mac with Ofast and O3 [1]. Some
microbenchmarks like Netty’s HttpObjectEncoder experienced >100% speedup with
O3, and the more real-world Dacapo suite was ~15% improvement over O2 (which is
exactly the same as Os). I did include a few other flags, howeve
I compiled with clang since I'm on Mac.
The Renaissance benchmark suite is also a good one that I learned about
recently.
My opinion is that there are probably more compelling alternatives if
reducing binary size is the goal. Even if the tests show that Os/O2 is no
different than O3, who knows if

Thanks for clarifying, that’s what I thought .

experiments )

That's good idea; I'm also curious about PGO. I know some apps get 10-20%
performance boost, however setting up PGO is pretty inconvenient. But maybe
having it run over the DaCapo / Renaissance benchmark
Dear JDK OpenJDK Team,
FYI since changeset 57501:dd4b4f273274 (8234794: AArch64:
runtime/memory/ReadFromNoaccessArea.java crashes) the build on arm32 seems to
be broken:
* For target hotspot_variant-server_libjvm_objs_BUILD_LIBJVM_link:
