Almost every ping has completely different times.
Hmm. I generally avoid bridged mode. I've used it once and once only (when virtualizing an OS/2 box that had had a parallel-port printer that it was providing as a network printer), and have since switched it to NAT (after a transitional phase, at the end of which I handed control of the printer over to Linux). It seemed to offer poor performance, so maybe I had the same issue you had. Is it any different if you switch to NAT?
