It could be very quiet (i.e., machine runs with no errors) and it could have bursts where it reports a large number of errors back-to-back depending on access patterns, DIMM health, temperature, sea level and at least a bunch more factors.
So I can imagine buffers filling up suddenly and fast, and userspace having hard time consuming them in a timely manner.
Every byte counts in such cases.
