What Hacker News says
8 sourcesWe're not running at scale, at least not the kind where performance of the library is likely to be an issue. We have around 50 tenants with a handful of users each. Tenants have up to 100's of millions of rows in Postgres - not exactly big data levels, but pretty big still.
I don't have perf numbers anymore, but I did some performance testing before I started using it a few years ago, and even back then it was much faster than EF/EFCore. The team have made many performance improvements since then. Considering the ease of use, and the fact you get NoSQL-style JSON documents that work alongside regular relational tables, basically the performance impact is as good as neglibible, IMO.
If you want to work with JSON documents, I highly recommend Marten.
It does have a Benchmarks project if you'd like to run some tests[0], and I'm sure the team

For what it's worth, site is great, I love it and will most likely use it, I just don't see why my email is needed.
In Show HN: Projects Made with CodeI was recently informed [0] about Marten [1,2], which is like RavenDB but uses PostgreSQL for the backend.
