After #8620, there is a noticeable slowdown in `EqualsBenchmarks.equalsTrees` as suggested in https://github.com/enso-org/enso/pull/8620#issuecomment-1870776609. After some digging, I realized that the number of warmup iterations is most probably insufficient. Let's increase the warmup for this benchmark and see if we can get its score down again.
