The zstd CLI produces deterministic output regardless of the number of threads used. `-T1` (or not specifying `-T`) will produce the same output as `-T0`. `-T0` will be faster for large files (at the default level, multiple jobs will be spawned for files > 8MB), and be just as fast as `-T1` for smaller files.

Best,
