ping - zasto prvi ping traje duze??

moze li neko objasniti zasto kada pokrenem ping naredbu od 5 paketa, te 1000 bytea na drugi komp, vrijeme slanja prvog traje duze nego ostali? Kompjuteri su povezani preko rutera.

# ping -c5 -s1000 192.168.1.12
PING 192.168.1.12 (192.168.1.12) 1000(1028) bytes of data.
1008 bytes from 192.168.1.12: icmp_seq=1 ttl=63 time=3.10 ms
1008 bytes from 192.168.1.12: icmp_seq=2 ttl=63 time=0.664 ms
1008 bytes from 192.168.1.12: icmp_seq=3 ttl=63 time=0.669 ms
1008 bytes from 192.168.1.12: icmp_seq=4 ttl=63 time=0.675 ms
1008 bytes from 192.168.1.12: icmp_seq=5 ttl=63 time=0.675 ms


A kod pinganja s 10000 paketa vrijeme prvog pinga je ujednaceno s ostalima?
