You don't seem to understand the idea that CPU spending time on TLB misses and at the same time seeing no measureable effects in E2E performance because much larger bottleneck is elsewhere can be both valid simultaneously. In database kernels with large and unpredictable workloads, high IO and memory footprint, this is certainly easy to prove.

I think you're moving the goalpost here. There's a measurement improvement to CPU usage. You're over-provisioned on CPU and don't care. Fine.
