Ok. Happy Vacation :)
Also, thanks for > continuing the benchmarking. Question, when you compare PLE vs. > non-PLE, are you using different machines (one with and one > without), or are you disabling its use by loading the kvm module > with the ple_gap=0 modparam as I did?

But older non-PLE results were on a different machine altogether. (I had limited access to PLE machine).
