It's not clear that graph-bench in "Tested with the LDBC Social Network Benchmark via graph-bench" is a benchmark that you made. It seems more robust and reliable than "we built a db and a benchmark tool, and our benchmark tool says we're the best". Just a thing to be careful about. You should just state that it's your tool and you welcome feedback to help make it so that other projects being compared are compared in their best light. Something like that might help, I don't know though it's a hard problem.
Strong chance the same robot that wrote the benchmark also wrote the sentence to sound impressive.
This is another one of the vibe-coded slop projects that are routinely frontpaging HN now. As someone else pointed out, the single author has "written" >100kLOC in diffs per week. It's not possible that any human knows what's in the codebase in any reasonable detail.
