This indicates that âmax_threadsâ is 2. By default, Sledgehammer will use only as many cores as are reported to it. âmax_threadsâ itself is set up through various options, about which I have little clue. If you have more than 2 cores on your machine, something is fishy.

Incidentally, this behavior of Sledgehammer is nothing new. Is the issue really new with Isabelle2015-RC0? What happens if you write

    ML {* Multithreading.max_threads_value () *}

in Isabelle2014 vs. Isabelle2015-RC0?
