Compared to what? A single-threaded solution? I do think that
multi-threading creates a higher CPU load, and if you manage not to
block in system calls when there is work to and, and to avoid
busy-waits, that a single-threaded application will have higher
performance than a equivalent multi-threaded one.
Threads are for convenience, not for performance.
