The number of internal + table locks has increased from 16 to 64. This makes it + four times less likely that two concurrent processes + writing to the same table would collide and thereby + serialized. The cost is an increased constant memory + footprint for tables using write_concurrency. The memory + consumption per inserted record is not affected.
