https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=292265 --- Comment #11 from Stefan Roesch <shr@devkernel.io> --- Once the test program was running, I waited until it reached the pause statement, I queried the number of current superpages: [shr@freebsd-dev ~]$ sysctl -a | grep vm | grep large vm.pmap.large_map_pml4_entries: 8 vm.largepages.1G: 0 vm.largepages.2M: 16 vm.largepages.reclaim_tries: 1 The same can also be achieved with: dtrace -n 'fbt:kernel:shm_largepage*:entry { @k[probefunc] = count(); }' -c ./test-sp So the program is using superpages. I guess its time to look into procstat. -- You are receiving this mail because: You are the assignee for the bug.home | help
