Tsz-wo Sze commented on HDDS-4454:
----------------------------------
Streaming is around 2 times faster than Async for a single client and 3 times
faster for 3 clients; see "20220702_Single Client - Benchmarks for Ozone
Streaming.pdf" and "20220702_3 Clients - Benchmarks for Ozone Streaming.pdf

> https://issues.apache.org/jira/browse/RATIS-979 implements streaming
> semantics in Ratis.
> Currently, ozone write pattern is bursty and involves multiple buffers copies
> as well multiple ratis log syncs in a block write. The idea of the Jira is to
> use a zero buffer copy based ratis streaming in ozone write path for better
> performance and resource utilisation.
