currently, we notice, MLPerf storage still leverage page cache a lot, not stress storage enough. can we support one branch that issue direct IO for all places? I see there are too many file open places.

I don't think it makes sense as the goal is to reproduce a workload not to get maximum throughput out of the storage.
