Could you please put this optimization to state snapshot first and we can measure the overall performance difference then?
I guess it's easier to adopt the change there as the first step.

Do you think this pull request is ready for review? I can set up a benchmark to see the performance difference if so.

In state snapshot, the process of rebloom is asynchronous, and so it will be no improvement for overall performance.

Yes, Its ready for review I think.

But I recently notice that this PR(#29991) add hash cache for difflayers and it seems more reasonable than bloomfilter.

So this PR should be closed if PR-29991 merged.
