Tried that. Makes no difference to scatter of return time on the client. Do not know if that means that interrupt coalescence is still on, or that it makes not difference. The problem appears to be in the receipt of the packets, not the transmission (although I guess it could still coalesce interrupts on receipt as well. ) _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
