Hi
I posted my question earlier also but no one replied and I am not
getting enough information on squid website also. So pl reply to me.
Below is my question and configuration
I am using class 3 delay pool and objective is to allocate 128kbps to
each host which belongs to 10.60.0.0/16 subnet.
Below is my configuration
acl only128kusers src 10.60.0.0/255.255.0.0
delay_pools 1
delay_class 1 3
delay_access 1 allow only128kusers
delay_access 1 deny all
delay_parameters 1 -1/-1 -1/-1 16000/16000
Questions :
1. I noticed users get 128kbps bandwidth when they do download. But I
also noticed when I do normal browsing, peak some time goes high up to
600 kbps or 700 kbps. I used Packet shaper to monitor end user bandwidth
usage. So I want to know what is the policy, why I am seeing peak up to
600 or 700 kbps??
Where are you doing this monitoring? Between the Internet and Squid or
between Squid and the clients. Cached traffic is not affected by delay
pools.
2. I want to know if there is any command in squid to check how many
users are falling in delay pool policy etc. this will help in doing any
troubleshooting.
Either use the squidclient on the proxy to access the cache manager...
/path/to/squidclient cache_object://localhost/menu
...or set up a web server with the cachemgr.cgi and give it access to
your cache. Look for a menu object relating to delay pools. I don't
have a server set up with delay pools, so I can't be more specific.

Thanks Chris
I am seeing peaks between Squid and Clients. Is there any way to force
cached data also to go thru delay pool?
You might be better served by a traffic shaper (such as tc on Linux or
dummynet pipes on FreeBSD). As far as I can tell, delay pools are just
designed to preserve traffic between Squid and the internet.
What is delay_initial_bucket_level. If I make it 0 or make it 100 , what
will happen? Pl give some example. I have read FAQ and other documents
but I couldn't understand this.
Considering you have defined the same maximum and restore bucket size,
this parameter is meaningless. If you gave a larger maximum bucket
size, this would determine how full the maximum bucket would start with
a new client.
Another thing which I want to know is - Is delay pool going to take more
resources from server? Do I need to add more memory or CPU? I am
planning to use class c delay pools. And I have nearly 3000 users.
unquestionably, more resources will be required (Squid is being required
to track more information). I can't possibly begin to tell you how much
though.
