> (When I am working on scm ratislog parser (HDDS-5842) I see log segments are created with very small files.
> Then I remember this config(ozone.scm.ha.ratis.segment.size and preallocated.size), and some changes done in OM to improve perf when it is set to 4MB. For more info refer HDDS-3900
> With small files it has some performance affect, so we need similar change for SCM, as same reasoning can be applicable for SCM also.
