-----------------------------------
[~ssa], thanks for benchmarking Ratis and Ozone and filing this JIRA!
> ... up to 30% for relatively slow drives ...
Could you provide the detailed numbers and the benchmark setup? Then, other
people could try reproducing it.

> RATIS-2235 made append processing synchronized. That made Apache Ozone write
> operations slower (up to 30% for relatively slow drives). We haven't seen any
> issues with parallel processing, so it might be reasonable to make it
> optional.
