> 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).
