> While writing the records, RecordSerializer is the only owner of the `Buffer` 
> into which data are written. Yet we are synchronisation twice per record 
> while accessing MemorySegment. Removing this synchronisation speeds up the 
> Network throughput in point to point benchmark by a factor of two (from 
> ~12500records/ms up to 23000 records/ms).
