I started profiling on a new machine that is an exact

with earlier to rule out any machine-specific problems.  I 
pulled master and ran new comparisons with THP enabled at 
c418de93e398 ("Merge branch 'x86/mm'"):

  CONFIG_NUMA_BALANCING disabled	136521.55 SPECjbb2005 bops
  CONFIG_NUMA_BALANCING enabled		132476.07 SPECjbb2005 bops (-3.0%)

Aside: neither 4739578c3ab3 ("x86/mm: Don't flush the TLB on 
#WP pmd fixups") nor 01e9c2441eee ("x86/vsyscall: Add Kconfig 
option to use native vsyscalls and switch to it") 
significantly improved upon the throughput on this system.

Could you please send an updated profile done with latest -tip? 
The last profile I got from you still had the vsyscall emulation 
page faults in it.

Thanks,
