I can't seem to reproduce that (with a build of the current master). Maybe I'm doing something wrong? What I did was downloading the necessary source files, then: rustc -O combinations.rs rustc -O mmap.rs rustc -O -L . anagrams-hashmap.rs rustc -O -L . anagrams-hashmap-mmap.rs rust run mk_anadict.rs The generated dictionary has 161642 lines. Results: doener@atjola:rust-play $ time ./anagrams-hashmap wachsames 27 real 0m0.686s user 0m0.672s sys 0m0.014s doener@atjola:rust-play $ time ./anagrams-hashmap-mmap wachsames 27 real 0m0.057s user 0m0.051s sys 0m0.006s Times don't change much across runs.
