Well, 'of course' one might say... ;o)<br><br></div><div class="gmail_default" style="font-size:small;color:rgb(51,51,153)">What surprised me most that they claim to use less resources AND perform better. That particularly strikes me because usually ot favor one side, you take blows on the other one.<br><br></div><div class="gmail_default" style="font-size:small;color:rgb(51,51,153)">To me, the problem of such tests is that they are a mix of realistic/unrealistic behaviors, the first being invoked to justify useful conclusions, the latter to make a specific environment so that features from the Web server (as opposed to other components of the infrastructure) are tested.<br><br></div><div class="gmail_default" style="font-size:small;color:rgb(51,51,153)">They are arrogant enough to claim theirs is bigger and paranoid enough to call almost every other benchmark biased or coming from haste/FUD campaigns.
