After fixing my gcc stupidity Elapsed: User: System: CPU: high pte: 49.962s 578.888s 99.048s 1356.2% lowpte: 49.630s 576.242s 90.158s 1342.0% ukva: 50.122s 577.164s 88.958s 1328.4%
The increase in elapsed is probably within tolerances. The system time isn't :) The decrease in system time compared to lowpte comes because the PTE pages are allocated in highmem, and are node-local.
Differential profiles are up in a bit.
