    Hi all,

    I've been experiencing really slow internet and web browsing speeds on my iMac for a while now and it wasn't like this when I first owned it.

    It's extremely frustrating having to sometimes wait over 10 seconds to just load one webpage.

    I'm better off using my iPhone as that loads the webpages almost instantly.

    Any help with this?

    PS I've already cleared the caches and turned off all extensions but that hasn't helped at all.

    Thanks in advance.

    Random questions:
    - How much free space is left on your hard drive?
    - If you are connecting via wireless, have you tried an ethernet-based connection to see if that changes anything?

    There are many factors that contribute to the issue you are facing.

    Loading websites on mobile devices may seem faster because a lot of website developers have separate mobile sites setup for that reason. The content may not be as rich when viewed on a computer's browser hence the reason it's more responsive and loads much quicker.

    Do you face the same issue when browsing on another computer in the same network? if yes, we'll need to look at the network further.

    if not, try loading your iMac in recovery HD, choose "Get Help Online" in the main menu option and see if pages loads quicker there.

    if the issue persists, it could be a hardware related issue(i'm guessing the network card)

    You can also try using Google Public DNS to test, if the issue is resolved using Google DNS, the fault lies on your ISP DNS servers and only your ISP can do something about this, otherwise you can just keep using the Google Public DNS.

    Have you done any speedtest to test your connection too? You probably want to do that to have an idea the speed you are getting - www.speedtest.net

    Thanks for the replies so far.

    First off, I have about 500gb left on the terabyte HDD.
    Secondly, I'm using ethernet.

    And no, I don't experience the slowness on other computers that are connected to the same network. Also, I've loaded the exact same desktop based web pages on my iPhone and iMac, and my phone is so much quicker still.

    Just to also add, that I'm getting 50mb DL and 3mb UL on SpeedTest, and my ping on ping test is about 15ms

    - Have you tried in recovery and tested it?
    - You may also want to run traceroute test on both your mac and PC and compare the readings.
    - Also, explore the DNS option too and see if that helps.

    Right, so I started in recovery and tried the same web pages and they were all so much faster! I don't think they were as fast as when I first got the mac, but still so so much faster.

    And now because I'm back to using the computer normally again, they're all slow.

    So what does that mean??

    Thanks

    At the top of my suspicion list would be the lovely malware known as GENIEO

    There is an MacApps online distributor that I suspect was the source of this getting ensconced on my late 2012 iMac. It wreaked havoc with my entire LAN.

    I suggest grabbing Sophos and or BitDefender (both free for Mac) and run complete scans. It couldn't hurt.

    I already have sophos and have ran full scans before but didn't help :(

    Check to see if you've a Safari plist file, this would be located in [Macintosh HD/Library/Preferences/com.Apple.Safari.plist]. If so, take it from where it is ensconced and place it on your desktop for temporary safe keeping.

    Restart the iMac and perform a reset of NVRAM/parameter RAM, then open Safari. It ought to recreate the plist file if it needs it. You may also try a Reset Safari procedure and see if those bullets kill the problem.

    I'll try that later, thanks.

    The safari reset hasn't worked.

    Start your mac in safe mode: Hold left shift key on startup until you see a progress bar on the screen.

    It's expected for system to start slightly longer in safe mode for all the background tasks happening while booting in safe mode.

    in safe mode, is it slow as well? http://support.apple.com/kb/HT1564

    If not, you may want to go through your startup/login items for any suspected processes.

    Brilliant that's really useful information. I'll give it a go later and report back.
    Praying it'll solve it and it's driving me insane and not the performance I'd expect for a £1,100 machine.

    Right, I've checked through the files and there is no com.apple.safari.plist

    Also, just tried safe mode and the webpages do load relatively quicker like this which is good. Having said that, I've disabled all login items already and it's not this quick as it is in safe mode.

    Any other ideas?

    Thanks

    PS Just to add, in my activity monitor, it says that I have 7GB of RAM out of 8GB and I'm only running safari and iTunes and Activity Monitor. Surely that's not right is it?

    Hi,

    the Safari .plist file is located at :

    Macintosh HD / Users / YourUserName / Library / Preferences

    Not :

    Macintosh HD / Library / Preferences

    To access your user Library : Finder, menu bar, "Go", press the Alt key to reveal the Library.

    Or hit Shift + Cmd + g, type in : ~/Library

    How to :
    - quit Safari
    - move the com.apple.safari.plist file to the trash, do not empty the trash
    - restart the computer

    Ok tried that and safari is still slow!
    Ah this is doing my head in.

    Would is be anything to do with the amount of RAM that is being used?
    At the moment, all that I have running is Safari and apparently I've already used 6.3GB of the 8GB available. That's not right surely.

    Internet painfully slow on my late 2012 iMac

    Did you check running services? You must select all services from dropdown menu. Once a hp printer deamon was causing me headaches until i spotted it.

    I'm running the free Yosemite trial. Although the internet was still very slow on Mavericks as well.

    I've just downloaded an app from the store called Memory Clean and when it first loaded up it told me I had about 600mb free and over 4gb was app data. I pressed Clean Memory on it and it freed up a lot of memory so now I have over 4GB free which is great.

    None of that has improved the speed in which the webpages load though :(

    PS and yes, RAM Pressure is all green

    ----------

    Ok, I've just uninstalled my three extensions and it's helped.
    All webpages load quicker than before. Still not as fast as when I first got the computer but an improvement over what it was just like.

    Sorry, no offense here, but these "Utilities" are non-sense.

    "Free memory is wasted memory".

    Mavericks and Yosemite are using a totally new way of handling RAM, see link above.
    No app can handle RAM better than the OS does. Period.

    Freeing memory can only SLOW DOWN your computer.

    Back to your problem, some thoughts :

    1. try another browser : this will help understanding if the issue is Safari related OR network setup related.

    2. try another account (new account or Guest account) : this will help understanding if the issue is user related or system related

    3. since your iPhone has fast Internet browsing, compare its network setup with the Mac's network setup.

    iPhone : Settings / Wifi, hit the "i" (info) button : what are the DNS settings ?

    Mac : System Preferences / Network ----> DNS server = ?

    Ok so another browser doesn't help at all. Same speed.
    Another account has the same speed.
    The DNS settings and servers are the exact same on my iPhone and iMac.
