    Description

      While investigating performance regressions in Bonsai M2 we observed a large amount of memory allocations while optimizing a query. In SERVER-80582 we observed that Bonsai had a significantly higher memory stall rate in a CPU pipeline, which can also indicate that the memory management is too heavy. We should look at this issue further and see what changes may be necessary to fix it.
