For starters you might want to fix these rates.
1024+1536+512+512+512 != 3072
Over allocating may be causing the high number of dropped packets, and
its at least worth fixing before trying anything else. Make sure child
classes rates never add up to greater than the parents rate, in your
case 3072Kbit. Beyond that though I don't see anything obvious. You're
using sfq which what I usually see recommended to increase the queue
size and avoid dropped packets.

Jody,
Thanks for your help. I changed the rules about child process and it
have no effect on ping time, my script now shows like the one it is into
the end of this email. Ping response:
Estatísticas do Ping para 172.30.0.1:
Pacotes: SENDED = 10, RECEIVED = 6, LOST = 4 (40% LOST),
Aproximar um número redondo de vezes em milissegundos:
Mínimo = 315ms, Máximo = 423ms, Média = 371ms
If I put this filter:
$FILTER match ip protocol 1 0xff flowid 1:10
Then I will have a very good response time from outside world server
(like pinging into a big domain like www.uol.com.br), but when I try to
ping into my own server (the gateway of my network) it returns that big
size time and a big lost:
Estatísticas do Ping para 200.221.2.45:
Pacotes: Enviados = 4, Recebidos = 4, Perdidos = 0 (0% de perda),
Aproximar um número redondo de vezes em milissegundos:
Mínimo = 17ms, Máximo = 21ms, Média = 18ms
