Safari outgoing connections over 50.  Is this normal?

At times, I have over 50 outgoing tracking connections via safari, and I think it slows down my computer.  Is this normal, and can I limit this?  I tried blocking them but eventually I couldn't access the search engines, eg. google.  I think this is excessive and should be limited, and some of the links look redundant to me.  Is this normal activity?

Every webpage (unless it is really old and poorly built) contains all kinds of embedded links, images, scripts and other content.  Every one of those embedded elements exists at its own URI.  When you open a web page, your browser gets the contents of the page, which includes all those embedded element URIs - which means that the browser then has to go and fetch each of them in order to be able to display them in the page when it is rendered in your web browser.
So yes, every time you open a web page, there will be a flurry of other connections - and the richer the content of the page you are loading, the more additional connections will be required to get all of its content.
Now I've never used Norton, so I can't really comment on it except to say that it appears to have a well-earned low reputation vis-a-vis Macs...but regardless of what security tools (if any) you use, trying to monitor HTTP connections while you are actively web browsing is going to be a collosal waste to time.

  • My N82 is always connected to WAP, is this normal?

    Hi there, I am on 02 and just got a new Nokia N82. I have noticed that there is always a packet data connection made to '02 Postpay WAP'. If I hold in the red key it asks me if I want to disconnect the data connection and when I select yes, it starts the connection again moments later and at the top left of the screen under the signal bar, there are 2 arrows pointing away from eachother with the letter "E" above it. Also whenever I finish a call I get a message saying 'packet data connection active' which is annoying me. Is this normal behaviour for the phone? When I went into active connections is says that the connection to 02 wap has been made for x amount of hours, and i never turn the phone off so it's always connected. Also it shows that data has been transfered and this worries me as I only get 1Mb allowance of WAP per month before I am charged for it. Any help on this issue would be much appreciated.
    Solved!
    Go to Solution.

    It does this to allow you to connect quicker. It shouldn't be costing you anything in data but it may be slightly reducing battery life.
    You can change it's behaviour in the following menu:
    Menu > Tools > Settings > Connection > Packet Data > Packet Data Connection
    Change it from "When Available" to "When Needed".
    If this has no effect it could be another program running in the background thats causing the connection to stay open. The most common cause is email software.

  • HT4628 my itunes update is taking a long time, so far over 10hrs, is this normal?

    I have just started to update itunes to the latest software version and it is taking a log time, 10 hrs or more so far. Is this normal.
    The blue update bar is compleatly full as if the upload is complete but is still running package scripts. Can any one advise if this is normal and i should leave it, or could there be a problem?
    thanks

    no, that is not normal, quit and try downloading again, if that does not work, trash the Itunes application, not any of the libraries, just the application and try downloading again. With a dsl or faster it should only take less than hour depending on your type of connection

  • New connection very slow - is this normal ?

    Hi
    I just had option 3 broadband installed today but seem to be stuck on an IP profile of 2 Mbps. It was supposed to be 6-8, probably 7 Mbps.
    The line is clean and I tried the quiet line and it was very quiet.
    I understand there's a 10 day bedding in period, but wouldn't it start high and go down from there ?
    How long will I have to wait at 2 Mbps ?
    Cheers

    2mb is the starting point. You need to stay connected 24/7 for next 10 days as that is initial training period. if still 2mb after training then come back to the forum. Bt will not help during training period

    My original iPad takes about 5 long seconds before responding to my finger tap in the safari window. Like I tap in Safari window, then count 5 seconds before I can begin typing my search words. Is this normal? I really don't remember it taking so long when I bought it, but it has been this way for awhile. I have closed all open apps many times to no avail. I just reset all settings and still 5 seconds. I don't have a lot on my iPad with plenty of free space available. Also, I have to click twice on many things that typically take one click. Like it highlights it with first click, then second click completes the action that normally would be done in one click, like Facebook like button. Like will underline with click one, then will change to like on second click. Do I need to try to restore from my computer?
    Thanks for any help!

    Ive tried that but when Im logged in I dont have all the permmisions I should have so it just runs the test for my usernames own little virtual world.  Ive been using macs for over a decade now and I have never had my computer do anything like this. while sitting in front of my screen I watched the mouse go to some personal files and change the permissions and then covered their tracks by changing the timestamp on the file dates back. I watched it happpen while all internet conections were off.  I had my identity stolen, my facebook password changed, my email accounts closed out. and my firmware password changed all within two weeks of the origninal boot date

  • HT4061 Hello my name is George.  I have a new replacement 5S that I received this morning.  At this time I have been backing it up from the cloud for over 3 hrs, is this normal?

    Backing up my replacement 5S has taken over three hours and progress indicator is at approx 15%.  Is this normal? Can I disconnect and return to the genius bar for a quick fix?  Can someone provide direction.  Thank you.

    Hey George,
    This is the information from Apple that addresses iCloud restore times:
    The restore process is taking a long time to finish.
    The amount of time needed by the restore process depends on your geographical location and the speed of your Internet connection. Even with a fast Internet connection, the restore process may need 1 to 4 hours per gigabyte to complete.
    If you're traveling between countries, the restore process may require more time than usual. iCloud is tuned to provide the best service when you're in the geographical location from which you most frequently connect to the Internet. When restoring from an iCloud backup, iCloud is tuned to provide the best service in the geographical region you were in when you created the backup.

  • HT1363 Got iTunes 11.0.2 and iPod classic. ITunes no longer connects to iPod - wiped all contents and there is no way to re-connect - is this normal?

    Got iTunes 11.0.2 - as far as I know the latest version. My iPod classic no longer connects - gone through all on the "help" still won't work. There is nowhere with the word "device" and the iPod has now been wiped clean. Is this normal with the new version?

    You might want to try connecting to another computer with an older version of iTunes. If it connects, reformat it straight away just in case before adding your songs back in. Otherwise, you might want to seek for help at the official iTunes stores in your country. Chances are that the iPod might be corrupted, though iTunes being the problem can't be ruled out either.

    no firewall at all, in win 8.1, turned it off for all networks
    ftp and publish works just fine

  • It has taken over 2hrs to update my new Iphone 4 to iOS5 and it's still not done. Is this normal?

    I have only had my phone for 1 week and wanted to  download a ringtone from itunes. I got a message that stated I needed iOS5 downloaded. I have tried to update this via itunes on my home computer but it's been over 2hrs and it's still not donw syncing. Is this normal?? I do have a lot of music on itunes is that the problem?? Thank you!

    Thankyou for the reply, the pop up window is labelled backing up ,I can see the progress line its really passed 3 hours still as mentioned about 10 15% progress .Please all i want to know is it worth continuing or its a waste of time.Its worth mentioning that since i've got the phone 2 years ago I've never updated it and the sole reason I'm doing it now is since 2 days ago i can't get my emails on my phone but i do get them on my PC.
    Went to an Apple store an advisor told me to update it as it might solve the problem.Although i did delete my account internet account then register it again , also turned the phone on , off.Unfortunately still can't get my emails on the move .

    When jailbroken, you cannot update the iOS on your device. The only way to fix it is to do a full restore through iTunes. Before you do this make sure you backup your device and everything on it.

  • It takes over an hour for the rental movies from itunes to download. is this normal?

    it takes over an hour to download. is this normal?

    Welcome to the Apple Community.
    That all depends on your internet service. 6 Mbps or better is recommended for HD rental content. 2.5 Mbps for SD. You can check your actual internet speed at speedtest.net.
    If you'd rather download SD content to avoid waits, you can change the type of content available by default in settings.

    You can get a thunderbolt to firewire adapter. You can then get a firewire 400 to 800 cable and put the old computer in target mode. Then you can follow these instructions.
