That would then indeed be an indication of excessive flushes. I.e. you may want to
simply track down which one (and why) gets triggered too often.

>For the good point(L0 git:06bbcaf48d09c18a41c482866941ddd5d2846b44), the L2 rhel_x64 could boot up less in than 90s.

Not sure what you're meaning to tell us here.
