10. performance
Performance between master and SCM-HA branch (without turning on Ratis) is shared here
We use the default configuration for master and 2823.
The write throughput seems to be constrained by hardware, e.g. DC network, which we haven’t dug further.
According to the slight differences between 2823 and master, the performance of the SCM HA bypass Ratis is close to that of pure in-mem SCM
11. security considerations
Security is not ready on the branch yet, therefor this feature is not production-ready. SCM-HA is disabled for secure clusters to avoid any security issues. (See HDDS-4978.)
