[Kevin Jacobs, on Neil's tuple-untracking patch]
It doesn't seem to make much difference in our app. There seems to be some speedup, but nothing dramatic. Turning GC on and off at the right times is still slightly faster.
I'm confused. You earlier said:
I've found one case where the garbage collector _does_ cause serious performance problems, and coincidentally enough it is due to the creation of zillions of cycle-less tuples. Our current solution has been to disable GC in some parts of our code, and then manually trigger collection at the correct points.
Now I'm hearing that turning GC on and off is only "slightly faster", and that the speedup is so small you're not even sure there is one ("turning GC on and off" is "slightly faster" than a trial where there "seems to be some speedup"). This is not "serious performance problems" except to nanosecond counters like me <wink>.
The good news is that another (unrelated) part of our code just became about 20-40% faster with this patch, though I need to do some fairly major surgery to isolate why this is so.
Keep us informed! I suspect you're suffering from an app that's more than 20 lines long; I try to stay away from those.
