The second largest source of noise in browse:news:cricbuzz story is clustered around v8 metrics.

Focusing on by_chrome:v8:heap:old_space:allocated_objects (other v8 metrics are strongly correlated with this), from 100 samples we observe the measurements clustering around 3 specific values:

A) 4.7 MiB in 11 samples
B) 5.4 MiB in 22 samples
C) 9.5 MiB in 67 samples
