Latencies are high at around 4ms when the packets do arrive. Further speculation yielded the following: a non hrtimer kernel will delay all packets by one jiffie due to the tx timer. For an unknown reason, an arp packet is lost, so further echo requests are queued up until the buffer is exhausted. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
