migspeed - Man Page
Test the speed of page migration
migspeed -p pages from-nodes to-nodes
migspeed attempts to move a sample of pages from the indicated node to the target node and measures the time it takes to perform the move.
The default sample is 1000 pages. Override that with another number.
Requires a NUMA policy aware kernel with support for page migration (Linux 2.6.16 and later).
