However, could it be that multiprocessor networking has taken a hit? Doing a lot of parallel RPC calls (in fact, showmount -e) from the i386 VM to multi= ple external hosts produces a load spike which I do not remember to have seen previously. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
