Delkou paketu to asi nebude:

# ping -s8000 cvsup.cz.freebsd.org
PING www.freebsd.cz (195.113.19.84): 8000 data bytes
8008 bytes from 195.113.19.84: icmp_seq=0 ttl=250 time=29.499 ms
8008 bytes from 195.113.19.84: icmp_seq=1 ttl=250 time=29.383 ms
8008 bytes from 195.113.19.84: icmp_seq=2 ttl=250 time=30.257 ms

Takze pokud chapu dobre, rychlost by mohla byt i 250 KB/sec.
Asi brzo zacnu patrat po uzkem hrdle.
