 Overall, PAE affects memory performance by a 15-20% ratio; this is particularly noticeable with sysbench and hackbench, where bandwidth and thread/process creation time are all slower.  Overall, PAE affects memory performance by a 15-20% ratio; this is particularly noticeable with sysbench and hackbench, where bandwidth and thread/process creation time are all slower.
   
 Userland remains rather unaffected, with differences in the 5% range; build.sh -j4 runs approximately 5% slower under PAE, both for native and Xen case.  Userland remains rather unaffected, with differences in the 5% range; build.sh -j4 runs approximately 5% slower under PAE, both for native and Xen case.

 In essence, there is not much to say. Results are all below the 5% margin, adding the balloon thread did not affect performance or process creation/scheduling drastically. It is all noise. The timeout delay added by cherry@ seems to be reasonable (can be revisited later, but does not seem to be critical).  In essence, there is not much to say.
