How would somebody simulate the block size for blocks received by Bitcoin Core to perform these tests though? The blocks are either 1MB or 4 weight units in size so it involves running it in regtest and submitting your own blocks en masse, and then you have to fork Core and change the code to allow for bigger size limits. I don't believe anyone has done this yet. And by the way I think that it makes more sense to benchmark resource usage in WUs instead of megabytes since new versions of the client doesn't have a concept of megabyte-denominated block size.
