Safari being REALLY slow or sometimes "Cannot find server"! HELP!

Right, i have the new 'Safari 4' but its being really slow.
When trying to load up webpages, it sometimes takes AGES to load a page, or sometimes it even comes up with the message 'Safari cannot find the server'.
I have 'LittleSnitch' installed so I can see when Safari is using the internet to either upload or download information and most of the time, Safari is sat there doing nothing and not downloading any information...
I have reset Safari to no avail!
Why might this be happening?

'Safari cannot find the server'
Generally refers to a DNS problem.
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /
Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )
Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:
This is Apple's guidance on iPv6:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html
Click on Apply Now and close the window.
Restart Safari, and repair permissions.

  • Safari is really slow in my mini Mac

    Hi!
    I hope somebody may help me figure out what i can do with my computer.
    - It is a mini Mac
    - OS X Version 10.9.2
    - Processor 2.3 GHz Intel Core i7
    - Memory 4 GB 1600 MHz DDR3 (what ever that may mean!)
    I have had it for almost 1.5 years, and for almost one year, Safari gets really slow, sometimes. Sometimes it works great, as if nothing, and sometimes it is so slow i cannot open any website at all.
    Emails download fine, and other programms download fine at the same time that safari is not working, so i dont think it is the internet. Also, other devises using the same internet work fine.
    Google chrome works fine, but i dont like using it because it takes too much RAM in the long term, and i have problems with Google Chrome in some websites like my bank. Firefox also works normally fine, but i also prefer the say Safari works (when it works)
    I have checked the Start up. There is no programme running in when automatically when i Log in my account.
    I have checked the Activity Monitor, and even though it is running a lot of programms that i dont really know, none of them is over 0%. And right now only Safari and Google Chrome are running over 2%. Google Chrome sometimes is taking over 30% CPU and hte Google Chrome Helper also, but normaly it takes less than 5%. Safari says many times, but they are all around 2%.
    I have read that the "kernel_task" (which i also dont know what it is) takes a lot of Memory RAM. In my computer it is using around 400 MB, which is 5 times more than the programme following it which is Safari with 80Mb. Seems a bit much, it i doubt that it is what is really slowing down the computer.
    Could it be a virus?
    Hoping that somebody may help. Thank you in advance!

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • Sometimes cannot find wireless networks??

    i've looked around on a couple messege boards, but they didn't seem to be exactly the same problem i was having.
    essentially, after waking up from sleep or hibernate, i sometimes cannot find wireless networks.  the wireless switch will be on, Fn + F5 says my wireless is on, yet nothing can be found.  strangely, when i try to turn off wireless, whether it's through Fn +F5, or the hardware switch, the light below the monitor remains ON.  basically, i can't even turn it off.  when i do click the button to try and turn off wireless, it gives me the busy cursor and eventually the whole menu disappears.
    the way to fix this is by restarting.
    just today, however, i suffered this same problem, even though i wasn't coming back from sleep or hibernate - it just lost connection randomly and then couldn't find any networks.  attempts to turn off wireless failed.
    is there a solution?  is this actually the same problem that was remedied by changing a power setting?
    thanks in advance.

    Yeah I'm having this problem too, with my antique T41 running XP. It used to be rock solid it seemed to change when I installed XP SP3.
    I have tried reinstalling the Intel drivers but that hasn't helped. It seems when it restarts after hibernate (and occasionally at other times, as with the previous poster) it somehow doesn't lock on to the signal or it gets confused in the protocol or something. It doesn't always happen though - about one in three.  Rebooting cures it...until the next time.... 
     any assistance / ideas most welcome, thanks.
    PS I'm using Windows Zero Configuration not Access Connections. That was a change some years ago that made it work better so I'm inclined to stick with that unless someone can tell me why not....

  • Cannot connect to iTunes store.Safari cannot find server

    Cannot connect to iTunes store.Safari cannot find server.I can't update my games and other applications cos iPad cannot connect to iTunes store.Please help

    Be sure you have a good WiFi signal!
    Try reset modem/router (disconnect from power for some minutes)
    Keep the Powerbutton and the Homebutton pressed at the same time until you see the Apple logo on your iPad screen.

  • Safari cannot open facebook, cannot find server.. why ?

    When I try to go to the facebook page, Safari cannot open it, says "Safari cannot find server"..."Safari cannot conect to server".. etc etc

    Double-click anywhere in the line of text below on this page to select it, then copy it to the Clipboard (command-C):
    www.facebook.com
    Launch the Network Utility application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Network Utility in the icon grid.
    Step 1
    Select the Lookup tab and paste into the address field (command-V). Press return. Post the output that appears below – the text, please, not a screenshot.
    Step 2
    Select the Ping tab and do the same. Please enter the same input as you did in Step 1. Don't use the output of Step 1 as input to Step 2.
    Important Note
    Some web browsers and mail clients will automatically convert a domain name such as "www.example.com" to a clickable URL, such as http://www.example.com. That will interfere with the test. If necessary, edit the input in the Network Utility window to remove any added characters.

  • I uninstalled Safari because it kept crashing and cannot find where to get a new installation. Do I have to reinstall Lion?and cannot find

    I uninstalled Safari because it kept crashing and cannot find where to get a new installation.

    There's no official download - the simplest thing is to reinstall via Recovery. That's only a problem if downloading 4+GB is difficult. Your files/data should remain intact, although you'd want backups in any case.

  • Hey, does anyone else see that Safari is REALLY slow today?

    Say, does anyone else see that Safari is REALLY slow today?

    No problem with Safari here.
    Empty your Safari cache and try resetting Safari.
    Not enough free space on the startup disk can slow the system down including browsers.
    Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a minimum of 15% free disk space.

  • "Cannot Find Server" Constant Error Message

    I've been having this problem for quite some time. I will attempt to connect to a website only to wait forever and then get a "Cannot find server" error message. It's not just with one site, it happens with many.
    It's also random. Sometimes everything connects fine and fast, and then inexplicably I get "Cant' find server" for sites like Facebook, Amazon, even Apple. It can start working again for a few minutes and then in an instant I'm getting error messages again.
    However, my email always works fine.
    And this is NOT a Safari problem. I also get the same trouble when I switch to Firefox or Explorer. My ISP says it's an Airport / Mac issue since it all works fine if I direct connect to the laptop and because my email is also working.
    In addition, when I'm having this problem, my iPhone also cannot connect to the WWW but can get email.
    I've tried powercycling the modem and the airport numerous times. It's really becoming a pain.
    Any thoughts?

    Me too I tried everything. I am an Apple fan with 2 computers,3 iPods. I have no idea what the problem is. I had to re-run the disk each time to find the internet. Finally tried a Linksys Grouter worked first time-laptop anywhere in the house strong signal. I have had similar problems with an Airport Express-never got it to work-so tried the Extreme. I returned it-I didn't want to but I just could not get it to work.

  • HP Laserjet 2015 ..."Cannot Find Server"

    Thank you Garland_M for replying.  
    I have since removed the Printer Server, and found that I can simply put the USB Cable from the Printer to Computer 1, and Computer 2 will see it on the Network..... so I didn't even need that Printer Server in my setup as I had been informed.

    rkaufmann87,
    The printer that I have does not have network capabilities built in.... to have the network capabilities, HP says an additional piece of equipment must be used.... in my case, an HP JetDirect 175x Print Server... I found a used one on eBay that was inexpensive, so I purchased that, and have been trying to configure it to my computer and printer for about 5 hours now.... all I got were error pages.
    I have an older iMac (2008), and I wanted the ability of the use of one printer for the new and old computers.
    After I read your advice, I disconnected the HP JetDirect 175x Print Server entirely, and used just a USB cable from the printer to the computer. 
    The printer worked great from my new computer, but I still wanted the ability of using the printer with the older computer (Wi-Fi). I went into the Print & Scan of System Preferences, and for the heck of it, I clicked the "Printer Sharing" box. 
    I went to the old computer, and for the heck of it, I tried printing something.... LO & BEHOLD it worked. 
    I don't know how it works, because as I said before, the printer is not network-ready.  When I bought the printer several years ago, there were two printers of that model on the shelf.  One was a HP 2015, and the other was a HP 2015n.... (n meaning network).  At the time I didn't think that I would ever need a network printer, which was more expensive, so I purchased the non-network one.
    Now I am truly bewildered as to how I am able to print from both computers without the HP JetDirect 175x Print Server.
    Do you, or anyone else have the answer to that????

  • IE returns "Cannot find server" page during Servlet processing

    I have 2 JSP applications, that require a certain amount of server processing before they complete. For small amounts of information, both of these applications work fine. However, with larger amounts of processing, IE seems to timeout or have a problem maintaining its session and returns with "Cannot find server" - the actual server processing continues meanwhile. This only happens with IE - other browsers maintain persistence. The "timeout" is always consistent - 5 minutes or so with one of the applications, 13 minutes with the other.
    I can find no IE configuration that controls this. Since this doesn't happen with other browsers, is this an IE problem or a design issue with the application that doesn't manifest itself with other browsers ?

    I wouldn't call it an IE problem. I would call it a design issue -- you should not take that long to return a response to the browser. Instead, you should return an immediate response that says something like "Your request has been received for processing", and have some other thread processing requests off-line. That other thread should send a notification (by e-mail?) to the user when the request has been processed, including a link where the data can be accessed.

  • Forms/4GL Tutorial Returns Cannot find server or DNS Error

    Hi:
    I am trying to plow through this tutorial (10.1.3.1.0) and when I run the SRList.jpsx page I receive the error: Cannot find server or DNS Error. The URL produced by JDeveloper is:
    http://192.168.99.36:8988/SRTutorialADFBC-UserInterface-context-root/faces/app/SRList.jspx.
    Any suggestions?
    I've culled the forums and the Web, and cannot find a match. The only nugget that I can add is that I'm using JDeveloper with the OA Framework extension. I have been successful creating pages with OA Framework and executing them. Is there some incompatibility with OA Framework and ADF?
    Any help is greatly appreciated!

    Mchrist,
    You cannot use the OA Framework download to develop ADF apps.
    I would create two batch/command files: in each one, set JDEV_USER_DIR and any other environment variables to point to a proper place and run the JDeveloper.
    Just unzip JDev and OA Framework to separate locations and ensure that the user directory for each is in a separate location as well.

  • Cannot find server error trying to download Migration Workbench

    I've been trying to download OMWB for the last 4 days, from Oracle Migration Workbench Downloads / Release 9.2.0.1.2 for Microsoft Windows 98/NT/2000/XP page.
    Keep getting 'Cannot find server' and 'Page cannot be displayed' errors in Internet Explorer.
    Is this the correct URL:
    http://download.oracle.com/otn/nt/omwb/92012/omwb_92012.exe
    I downloaded and used the previous version of OMWB. Was very satisfied with it. Unfortunately, I had to rebuild my hard drive and lost OMWB.

    I suggest that you retry, maybe there was some network glitches... If you follow the links from OTN you should be able to download no problems. Did you try the split downloads as an alternative?
