There was a large performance regression that was bisected to commit 611ae8e3 (x86/tlb: enable tlb flush range support for x86). This patch simply changes the default balance point between a local and global flush for IvyBridge. In the interest of allowing the tests to be reproduced, this patch was tested using mmtests 0.15 with the following configurations configs/config-global-dhp__tlbflush-performance configs/config-global-dhp__scheduler-performance configs/config-global-dhp__network-performance
Based on these results, changing the default for Ivybridge seems like a logical choice. Signed-off-by: Mel Gorman <mgorman@xxxxxxx> Reviewed-by: Alex Shi <alex.shi@xxxxxxxxxx>
