When running the data analytics benchmark on an aarch64 platform, we see the following in the log output:

23/11/28 14:52:33 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

Even though difficult to compare, from a first comparison with a nominally slower x86_64 instance (AMD EPYC) we see indeed better results on the x86.
