I had accidentally TEXMFCNF set in my environment (from previous tests). Testing some more with this environment variable of TeXLive unset, I get completely different results. % pdftex with (total): 5.46095pt without (total): 5.43422pt with minus without: 0.02673pt % luatex with (total): 6.10898pt without (total): 6.03908pt with minus without: 0.0699pt And re-setting it (to "$(pwd)") I reproduce again typically the above results... i.e. with TEXMFCNF set its is advantageous to use \romannumeral, both with pdftex and with luatex. with TEXMFCNF not set, it is disadvantageous... ... that’s highly baffling to me ! I repeated quite a few times to make sure timings are consistent, it seems with luatex it is, with pdftex less so ok, I don’t want to induce people to lose time on ill-conceived test
