      Description

      At AWS re:Invent 2019 last week, AWS announced new EC2 instances based on the Graviton2 ARM processor which apparently can be much faster than the original A1 instances, at least according to internal benchmarks.

      I've been running Lucene's benchmarks (wikimediumall, indexing 33.3 M docs and running a diverse and repeatable set of search tasks) on these instances, comparing a c4.8xlarge (x86-64) instance against the new m6g.8xlarge (ARM), and I'll summarize the results here.

      Net/net ARM seems to be faster at raw indexing than x86-64, even though m6g.8xlarge has only 32 cores versus 36 cores, but a bit slower at merging, while searching seems to be faster for some queries and slower for others.  I'll try to get the full results posted soon.
