What happened?

I noticed /usr/bin/time conda create -n tensorflow --dry-run tensorflow --solver=classic took 6.35 seconds on conda 22.11 but 9.25s on conda 23.11. (conda-libmamba-solver takes <1 second).

I poked around a little and got the following numbers:

22.11.0 with classic (avg. of three runs): 6.71 total 23.11.0 with classic (avg. of three runs): 7.67 total

I noticed the first runs with both version took a little longer. Just a little bit over 10s.
