> In the nightly benchmark, checkindex times increased more than 4x on the 2/16
> datapoint
> Looking at the commits on 2/15, most obvious thing to look into is docvalues
> terms dict compression: LUCENE-9663
> Will try to pinpoint it more, my concern is some perf bug such as every
> single term causing decompression of the whole block repeatedly (missing
> seek-within-block opto?)
