      I set the max object size very high to cache windows updates.  There is nothing worse than watching people sit at their desk while a 150mb .NET service pack downloads at 300K.

      u don't get it what i mean..
      cmiiw the file that u download 150mb.. it consist of a thousand packet..
      one packet maybe contain arround 256 kb

      what i mean is max object size is per packet.. not a whole file..

      i'm dumb.. but i have a desire to learn

        Hay, d-ifyouare, who told you squid would cache IP packets only? It is caching an entire object (aka file) from the likes of .html or .jpg or .png or.xml or …
        Looking at your squid cache folders you'll find objects of highly varying sizes. That's the size of the cached file. It wouldn't differ if its only packets.

          u're questioning about "who told me" that's juz my assumption.. that's why i said "CMIIW"
          ok so now my question.. someone refer that he's using cache for windows update..
          let's say person A he download windows update at speed 5kb and finish the update <–-- squid will save it as a cache right?

          and then person B download windows update too.. how aproximately the speed? is it as fast as file sharing?

            If you have a very busy network the file downloaded from windows-update might not be in cache anymore.
            If the network isn't very busy chances are the file will be delivered from squid cache (either RAM or HDD).

            Squid performance depends greatly on usage, hence the many caching policies and configuration option (not all implemented into the package).
            There is no simple configuration to satisfy all usage variables.

                    The cache will have two copies of the same file as they came from different URIs/URLs.

                    If you're worried about duplicate Windows Updates then you should be using WSUS or something like Heise's offline update.

                    In a business environment of any importance you should really be using WSUS to manage/track updates anyway.

                          This is how CDN works. It downloads the content from the different servers usually it downloads near to your location.
                          Thats why squid has storeurl feature to redirect them into 1 file.
