It looks like the problem have something to do with squid configuration. What I think is hapenning is that when a user requests a big file squid tries to dowload it as fast as possible using all the bandwidth available causing this the hogging on the line. I had the max_object_size to 512MB I changed it to 64MB to check if that might ease the problem but, I don't see any changes. What config option should I change to prevent squid to download the file as fast as is doing now? Or Could it be something else?
