The TeX Live guide  lists
Kpathsea: Case-insensitive filename matching now done by default
in non-system directories; set texmf.cnf or environment variable
texmf_casefold_search to 0 to disable. Full details in the
Kpathsea manual (http://tug.org/kpathsea).
The details are explained in  Casefolding search
In Kpathsea version 6.3.0 (released with TeX Live 2018), a new
fallback search was implemented on Unix-like systems, including
Macs: for each path element in turn, if no match is found by the
normal search, and the path element allows for checking the
filesystem, a second check is made for a case-insensitive match.
If you just want to go back, set, as described above, the texmf.cnf
variable or env variable
that should bring it back to the previous speed.
Hope that helps
