Can you measure a significant performance overhead? But it LGTM it's similar to #50600 which was going in the other way |

I believe it can make sweep times worse in the multithreaded binary tree GCBenchmarks. That's the cost of the increased number of |

We're suffering from heavy fragmentation in some of our workloads. Add a build-time option to enable 4k pages (instead of 16k) in the GC, since that improves memory utilization considerably for us. Drawback is that this may increase the number of `madvise` system calls in the sweeping phase by a factor of 4, but concurrent page sweeping should help with some of that.
