Recently, I became interested in a debugging option in the Linux kernel

slub_debug=p

``` Average Half load -j 2 Run (std deviation): Elapsed Time 44.586 (1.67125) User Time 73.874 (2.51294) System Time 7.756 (0.741741) Percent CPU 182.4 (0.547723) Context Switches 13880.8 (157.161) Sleeps 15745.2 (24.3146)

Average Optimal load -j 4 Run (std deviation): Elapsed Time 32.702 (0.400087) User Time 89.22 (16.3062) System Time 8.945 (1.37014) Percent CPU 266.4 (88.5729) Context Switches 15701 (1929.57) Sleeps 15722.2 (78.1875) ```

without slub_debug=p

``` Average Half load -j 2 Run (std deviation): Elapsed Time 40.614 (0.232873) User Time 69.978 (0.503061) System Time 5.09 (0.182209) Percent CPU 184.4 (0.547723) Context Switches 13596 (121.501) Sleeps 15740.4 (46.4629)

Average Optimal load -j 4 Run (std deviation): Elapsed Time 30.622 (0.171523) User Time 86.233 (17.1381) System Time 5.874 (0.853557) Percent CPU 270.1 (90.3431) Context Switches 15370.3 (1875.97) Sleeps 15777.4 (74.43) ```
