I ran the emacs test about 5 seconds after the command prompt test.
so I don't think windows would forget about the already loaded
DLLs in a such a short time.
I tried to trace the process and it seems to me when the search is run
via emacs then windows defender checks every source file read by ripgrep
and I assume this slows down the search.
When tracing an invocation via the command prompt then there are no checking
of source files, so it looks like windows defender thinks emacs is a suspicious
program or maybe it considers the invocation of cmdproxy.exe suspicious.
With windows defender turned off for the given source directory the delay
practically disappears.
