I've been testing with the TPC-H benchmark this morning.
Latest from master:
```
Running benchmarks with the following options: TpchOpt { query: 1, debug:
false, iterations: 3, concurrency: 24, batch_size: 4096, path:
"/mnt/tpch/parquet/100-240", file_format: "parquet" }
Query 1 iteration 0 took 16167 ms
Query 1 iteration 1 took 16012 ms
Query 1 iteration 2 took 16229 ms
```

That's around 15% speedup :rocket:
