  • Does this have anything to do with ticket #60692? I just repeated a run of examples/benchmarks/primes2.pir with current parrot and what used to run in 8 seconds before commit 31668, took 220 after that and now takes 133 seconds. What's so unusual evil about this program?

    • Yes, it has something to do with it. I knew we'd need an MMD cache at some point, though I didn't plan it for further down the line. A bunch of changes done in that commit (actually a branch merge) resulted in opcode dispatch in many cases going through the standard multi-dispatcher, where before they just were done with a 2D lookup table (which gets unsustainable when you get lots of types). The changes means that at least multi subs and ops dispatch the same way, which is good, but there were some issues.
