[squid-users] (mis)understanding delay pools?

Hi,

we're running the packaged Squid on Ubuntu LTS (2.6.18-1ubuntu3).

I've configured squid with a delay pool as follows:

  acl accommclients_old src 10.2.0.0/16
  acl accommclients src 172.17.0.0/20
  acl studentclients src 172.18.0.0/16
  acl studentwificlients src 172.19.0.0/23
  acl summerschoolclients src 172.19.4.0/24

  delay_pools 1
  delay_class 1 1
  delay_access 1 allow accommclients accommclients_old studentclients studentwificlients
  delay_access 1 deny all
  delay_parameters 1 2500000/2500000

which I thought would limit all of those IP ranges (together) to
2.5MByte/sec, ie 20Mbit/sec.

However, the other day, we found squid consuming over 40Mbit/sec. This was
mostly down to one individual user who was within the 172.17/20 range who
was consuming well over 30Mb/sec.

I presume I'm doing something wrong. Could someone point out my mistake or
suggest something I should look at?
