------- Comment #6 from paolo dot carlini at oracle dot com 2010-09-07 17:55 ------- By the way, I don't know anything about your testcase (it would be a good idea attaching something here, just in case), but on my machines, i7 mostly, I don't see anything similar to your performance gap, I see something more similar to 9-10x, which, considering that a real synced mode must be unbuffered, seems completely reasonable to me.
