The figure is based on our experience of running scope probes in production systems. Below this we see a lot of "conntrack stderr:WARNING: We have hit ENOBUFS! We are losing events."
There is no downside to a larger buffer size other than, presumably, higher memory use, but since scope probes typically weigh in at >100M RSS, adding a few extra M bufferspace is hardly a concern.
