I added -pipeline but I guess -with-batch is more explicit. I'll change it then. But anyway the techempower team will eventually add a special tag for batching. There is actually a version of lithium not using batching, check for 'lithium-postgres' in the benchmark tabs other than 'composite score'
Other big optimizations are
- non blocking communications between the database and the framework
- non blocking communication between the http client and the framework
This is for C++, for other slower interpreted languages: calling C bindings is a big optimization aswell (and this is how some php frameworks get good performances for example).
