This pretty much exactly matches our experience. I've also run some CPU-intensive benchmarks with direct linking on and off and seen almost no difference. We also quickly found it far better to run dev with it off, because otherwise you usually need to reload the world to reliably redefine a single function. Sidenote: if only I had the time, I would *so* love to jump in and try implementing this with JDK 8 switchpoints/method handles/etc [1]. With that approach we could have our cake and eat it too! Cheers, Matthew.
