I noticed some unusual results when comparing the graphs for node garbage collection for a 1 hour period vs a 2 hour period. The two graphs are below, and are taken at essentially the same time.
I'm confused why the 2-hour graph shows spikes almost to 40,000ms, whereas the 1 hour graph only shows spikes up to 30,000ms. Why would this be? I could understand a reverse situation -- where a 1 hour graph is able to show a greater level of detail (that maybe gets lost from a 2 hour graph). But this is the other way around (i.e. seemingly greater detail over the larger time period).
