Wow, I'm surprised. I suppose I do jump to thinking of heavy swapping when light swapping won't be so bad; but even so, 20x ext3 astonishes me - ext3 wouldn't be anyone's choice for fastest, but even so... I certainly guess too much and measure too little: is there a useful test you could point me to?
