delay_pools fail

[Carlos Manuel Trepeu Pupo <charlie.mtp@xxxxxxxxx>]

I'm using squid 3.0 STABLE1 on ubuntu 8.04, I have this conf:


delay_pools 1

delay_class 1 1
delay_parameters 1 15000/15000
delay_access 1 allow all

To limit all traffic to 15 KB, but the traffic reach 45, 60, 25 .....
What happening this ?? And how can I limit this ???
