 * `--hist` pointing to a fast location (ssd) will make directory listings and searches faster when `-e2d` or `-e2t` is set
 * `--no-hash .` when indexing a network-disk if you don't care about the actual filehashes and only want the names/tags searchable
 * `--no-htp --hash-mt=0 --mtag-mt=1 --th-mt=1` minimizes the number of threads; can help in some eccentric environments (like the vscode debugger)
