>> Do you have any large page (hugetlbfs) or other multi-order (> 1 page) >> allocations happening in the kernel? I forgot to address the second part of this question: How would I best inspect whether the kernel is doing that? Looking at the kmalloc() sizes from vmstat -m I have the following on one of the machines (so very few larger than 4096). But I suspect you are asking for something different? kmalloc-8192 52 56 8192 4 kmalloc-4096 33927 62040 4096 8 kmalloc-2048 338 416 2048 16 kmalloc-1024 76211 246976 1024 32 kmalloc-512 1134 1216 512 32 kmalloc-256 109523 324928 256 32 kmalloc-128 3902 4288 128 32 kmalloc-64 105296 105536 64 64 kmalloc-32 2120 2176 32 128 kmalloc-16 4607 4608 16 256 kmalloc-8 6655 6656 8 512 kmalloc-192 6546 9030 192 21 kmalloc-96 29694 32298 96 42 -- / Peter Schuller aka scode -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
