​Yes, by default Lwt has a backend using Unix.select, and a libev one if
 available at compile time (`opam install conf-libev`)
​. At runtime Lwt will use the Unix.select backend by default, except if it
was configured to choose the libev one (the default on Linux) [1].

There is also a backend using the glib main loop, for GTK applications
