This paper by by Jorge Zuniga https://arxiv.org/abs/2506.10321 contains formulas for single and multiple logarithms that may be faster than the ones we are using now; see in particular section 6.
This could notably speed up the precomputation stage of the multi-prime argument reduction for Arb elementary functions.
