Thanks for the tip.  I find that

context --make

takes quite a long time whether or not I'm running the command prompt as an administrator.  But when I compile my experimental file as administrator it now runs as fast as I would expect - so it is that that makes the difference.  Why this should be I cannot say (and am not going to spend time finding out!).

I do have an embarrassingly basic question about my test file which I'll post in a separate thread.

Best wishes

just try this after a fresh start:

context --make

context --make

and note the difference in reported time ... the operating system caches
files and programs like tex benefits from this

in the past when running on a network share - in most cases we use(d)
opensuse linux servers - using e.g. installations like texlive was
basically impossible due to the size which is why we had the minimal
distributions, also for pdfex/mkii; i think that over time kpse lookups
improved a bit but is is one of the reasons why we had agressive caching
in the runners (texexec etc) just so to limit the number of nested
kpsewhich database loading overhead and kept startup time bearable

in the meantime startup time of a context run in lmtx should be below .5
seconds and that includes the runner as well as the engine (and on
modern systems below .25 sec but i can't check that as i only have
laptop hardware pre 2018 to test on)
