    McAfee Web Gateway - SLOW UPDATES

    mmalagni

      All,

       

      in the last 2 days I'm having so many issues with the updates of McAfee Webgateway 7.3.2.6

       

      It's a really incredible slowness. It can take up to 5 hours to perform an update.

       

      Although the appliance is directly connected to Internet and the surfing through it is really performing.

       

      If I try to download from contentsecurity.mcafee.com/updates throught the Proxy the download speed is about 1,3 MB.

       

      Instead the download of the updates is an average of 20 KiBs from the proxy Webgateway.

       

      Any advice?

       

      Another thing, is there a way to suspend and update in SSH?

       

      Regards

       

      Matteo

            Hello,

             

            can you please provide one or two update IDs from your slow updates? You should be able to find them in the update.log that is written by MWG.

             

            Best,

            Andre

                Hello,

                 

                thank you. I was able to validate that you update against our european update servers, which is good. Unfortunately there is no hint why the download is that slow. What you can do is manually download a test file from our update servers and from the CDN. If you are able to SSH into one of the systems please change the directory to /tmp and run:

                 

                wget https://tau1-4.mcafee.com/updates/datfile.test

                wget https://mwg-update.mcafee.com/updates/datfile.test

                 

                Can you let me know the results of this? It should give you a response like

                 

                2014-03-19 13:04:33 (5.37 MB/s) - `datfile.test' saved [99983374/99983374]

                 

                Best,

                  Andre,

                   

                  the result is

                   

                  2014-03-19 13:11:16 (2.21 MB/s)

                   

                  That what we expect from our connection.

                   

                  Instead in the Gui that's the result:

                   

                  Proxy-3: download update files (10%), speed: 22 KiB/s

                  Proxy-4: idle

                  Proxy-2: idle

                  Proxy-1: download update files (7%), speed: 32 KiB/s

                   

                  And no error are present in the update_error.log or strange message in the update.log

                   

                  Regards

                    Hello,

                     

                    have you tried the "speedtest" against both servers (tau1-3.mcafee.com and mwg-update.mcafee.com)? The biggest files are transferred from mwg-update.mcafee.com which is a pointer to a Content Delivery Network. It is possible that you are directed to a cache that is slow, busy or has any problem, so the speed test against mwg-update.mcafee.com would be beneficial.

                     

                    Can you provide the full output of

                     

                    wget https://mwg-update.mcafee.com/updates/datfile.test

                     

                    please?

                     

                    Best,

                    Andre

                        Hi Matteo,

                         

                        immediately after your post I tried to obtain the test file from the same cache (IP) that is used for you and I was able to see the same performance problem:

                         

                        2014-03-19 13:56:35 (45,6 KB/s) - datfile.test gespeichert [99983374/99983374]

                         

                        Now 1 1/2 hours later I tried again and speed is a little better for me:

                         

                        2014-03-19 14:56:49 (4,52 MB/s) - datfile.test gespeichert [99983374/99983374]

                         

                        Do you mind giving it another try?

                         

                        The CDN we are using is provided by Akamai, so nothing we maintain on our own. It is likely that a cache may have trouble and also likely that Akamai solves those issues before we raise a case with them. Before I am going to raise a case, may I ask you to try again and let me know the output again (as you did above - full output with remote IP etc)?

                         

                        Thank you,

                        Andre

                          Andre, I tried also to change IP address in the host file for the AKAMAI server to another server. Just to check if they were blocking my connection.

                          Then I tried to download from another public IP and the result is exactly the same.

                           

                           

                           

                          Can we have access by any chance to the tau server? :-) or point to download updates to a specific address? Which one you are using in your better speed test?

                           

                          Regards
