But we can probably do > better for the fstring table, even. I'm trying this new hash table out. There should be other things to convert, and it can probably be tuned more. But it works, so far... The design is based on st, but uses linked-list of cache-sized arrays for chaining, so it's as if each bucket is an st-packed array. The top-level buckets are one big flat array, and metadata overhead should be low (users define entry size, so key/val need not be uintptr_t-sized). Delete-while-iterating is probably be slower than st, but I haven't tested that at all. -------------------------------8<----------------------------- ih: internal hash implementation + convert some larger tables Introduce a new internal hash (ih) with minimal storage overhead for use in internal tables where order does not matter. Performance does not seem greatly affected[1], but memory usage seems improved with only a few large, relatively static tables converted. Lightly tested, but passes "make check". running: /usr/bin/time ./ruby -v -e exit ruby 2.2.0dev (2014-01-12 trunk 44573) [x86_64-linux] before: 0.02user 0.00system 0:00.02elapsed 96%CPU (0avgtext+0avgdata 7432maxresident)k 0inputs+0outputs (0major+1931minor)pagefaults 0swaps after: 0.02user 0.00system 0:00.02elapsed 96%CPU (0avgtext+0avgdata 7196maxresident)k 0inputs+0outputs (0major+1874minor)pagefaults 0swaps Note the reduction in resident memory and pagefaults.
