Re: [squid-users] outside squid link overload.

Squid doesn't have such feature, data from web is read without
correlation to client BW status. It's an interesting feature but it
doesn't exist.
delay_pools are only toward clients and will not help for your problem.

The problem is that GRPS users start 2-3 downloads and Squid loads it very fast and put it to cache but user can load the objects from Squid only at 30-180kbit/s. So when I divert all GPRS users thru Squid, my internet link becomes stuck because Squid loads many files at all available bandwidth and then give it to customers at GPRS speed.
> Restriction by delay pool doesn't suit - users have different speeds (up to 230kbit/s), so if I restrict each to 230kbit/s - it won't help because 40kbit user will cause Squid to download at 230kbit/s. If I restrict to 40kbit/s, then 230kbit user will complain that speed is very low.
