Has anyone come across any solid explanation of why iphones, ipads, and ipod touches all seem to respond poorly to simple ping tests in terms of latency? Just pinging an ipad across a local home network yields horrible results e.g.
bjp$ ping 10.0.1.14 PING 10.0.1.14 (10.0.1.14): 56 data bytes 64 bytes from 10.0.1.14: icmp_seq=0 ttl=64 time=83.143 ms 64 bytes from 10.0.1.14: icmp_seq=1 ttl=64 time=105.490 ms 64 bytes from 10.0.1.14: icmp_seq=2 ttl=64 time=29.204 ms 64 bytes from 10.0.1.14: icmp_seq=3 ttl=64 time=46.337 ms 64 bytes from 10.0.1.14: icmp_seq=4 ttl=64 time=172.870 ms 64 bytes from 10.0.1.14: icmp_seq=5 ttl=64 time=93.284 ms 64 bytes from 10.0.1.14: icmp_seq=6 ttl=64 time=114.715 ms 64 bytes from 10.0.1.14: icmp_seq=7 ttl=64 time=39.345 ms 64 bytes from 10.0.1.14: icmp_seq=8 ttl=64 time=60.012 ms whereas pinging a wireless laptop client on the same network is fine.
