Hi Raghu,
sorry for my slow response. I'm on vacation right now (until the 9th of July) and I have limited access to mail. 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?
