Has anyone benchmarked Accumulo 1.10.1? I have been looking into repeating the measurements we did in 2014 with Accumulo 1.5 (https://arxiv.org/abs/1406.4923) using Accumulo 1.10.1 on a bigger system with more modern hardware. Unfortunately, when I repeat the single node measurements, there is no performance improvement from having multiple ingestors inserting into different presplits of a table. I get 120K inserts/sec with one ingestor and 2x60K inserts/sec with two ingestors. In 2014 we got linear speedup to ~6 ingestors, providing ~600K inserts/sec on a single node.
