It's about 1.5 times slower than pure async ADO.NET using IConnection and IDataReader, implying (duh! :D) it's about 5 times faster than Python and twice as fast as PHP. As to memory, we're running our cloudlets on "dust" basically, still they perform better than the average PHP solution deployed into 10x as much HW.
It's also async to the core, implying it's probably about one order of magnitude better on throughput per HW compared to PHP and Python, possibly more.
To understand why, realise it's just a tiny abstraction on top of .Net version 6. Implying we've got almost the same traits in regards to performance as .Net 6.
