Tantalizing, but on investigation I see that our real application actually does very little explicitly with reverse or conj, and I don't actually think that we're getting reasonable speedups (which is what led me to try that benchmark). So while I'm not sure of the source of the problem in our application I think there can be a problem even if one avoids direct calls to reverse and conj. Andy's recent tests also seem to confirm this. BTW benchmarking our real application (https://github.com/lspector/Clojush) is a bit tricky because it's riddled with random number generator calls that can have big effects, but we're going to look into working around that. Recent postings re: seedable RNGs may help, although changing all of the RNG code may be a little involved because we use thread-local RNGs (to avoid contention and get good multicore speedups... we thought!). -Lee -- You received this message because you are subscribed to the Google Groups "Clojure" group.
