I thought ocaml's "threads" are meant to solve the I/O problem. Doesn't it use native pthreads for each OCaml thread, and prior to performing I/O it releases the mutex allowing other threads to run? Of course you'd still have to wait for the I/O to complete to serve the file to one particular user, but in the meantime you could serve some other (already cached) file to another user, generate some dynamic content, etc. Lwt's Lwt_preemptive seems to allow one to use 'preemptive threads' (which I assume are just usual OCaml threads). So would it be possible to put the file I/O on Lwt_preemptive.detach threads? Has anyone tried to measure the performance of doing that?
