Slow network timeouts, page loading when host is bad

I just got a new iMac, and it takes a long time to timeout network connections to bad hosts. For example, on the Mac it's replacing I can just type "apple" into the Safari address bar, and since that's not a real address Safari would be smart enough enough to almost instantly replace it with "www.apple.com". The new iMac takes 30 seconds to do this. It causes a number of web sites to load slowly since quite a few seem to pull non-essential resources from other servers that aren't always up (ads, scripts, etc.).
I can verify that it takes 30 seconds by running "time ping apple" in the Terminal, which takes almost exactly 30 seconds each time before saying "cannot resolve host". The old Mac fails instantly. Can someone else try this on Snow Leopard an let me know if it's fast or slow for you. I restarted in bootcamp/Windows 7 and I do not have this issue there: 'ping' times out right away.
I don't think this is a DNS issue since the two macs have the same DNS server. Also, "nslookup apple" on the new Mac immediately says "can't find apple," like I'd expect.
Any ideas on what causes this delay? Is this a configurable network setting somewhere? The new Mac is on Snow Leopard; the old is on plain Leopard. I'm not going through any proxy servers or running any ad blockers or the like.

Server timed out while loading the home page.Loads when refreshed.

Hi All
I have developed my application in .Net framework. I tried to deploy the application in PlumTree Portal server. The application gets timed out when run for the first time ( i.e, as soon as user logs in). It gets loaded when the page is refreshed. I tried inreasing the portlet timeout in web service, but of no use.
I have used "Response.Redirect" in my home page to load the screen as per the user. Could this be a problem? Or is there a problem an someother place.
Any help or suggestion is welcome
Thanks,
Karthick

Hey jennifer,
Did you ever have this issue solved? If so, please post how did you figured it out. I'm having the same problem.

Slow start and page load on 10.8.5?

I recently upgraded to 10.8.5 from 10.6.8. It now takes several tries to get the system to start, and page loading on the net seems slower. Is this normal?

No.
Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

My Firefox is impossible to use. It is very very slow to change pages, load pages and so one.

I already search and applied several suggestions found in Internet, but until now, no one solve the problem. Firefox is using much memory (600.000) and much CPU (100%) and work very slow to load new pages or update the pages loaded.
I am using APP "Memory Fox" but is the same.

hello VictorTrindade, please try to [[Reset Firefox – easily fix most problems|reset firefox]] and see if this can address the issue...
please also make sure that firefox isn't blocked by your security software/firewall in any way.

Why cannot I have my personal page load when I open Firefox

On Safari, my home page opens when I log on, and I can read my email. I would rather use Firefox, but I get my ISP's Generic home page, and have to supply my Screen name and password every time I log on, which is a nuisance.
Can this be corrected ?

Check the Home page setting.
*Tools > Options > General > Startup: Home page
See these articles for some suggestions:

High error count, slow or no page loads

My apologies if the formatting of this is rubbish - posting from work and our firewall is blocking some features, so it looks awful here! Hi, I hope someone can help or advise with my ongoing Broadband speed issues. To summarise the story so far: Last week (19 July) I initiated the change from my then provider (Namesco) to BT by giving the MAC code. Changeover day was given as 1 week later, 26 July. 2 days later my BB connection went very slow. Pages would not load or would only load very slowly. Speed tests (when it would load) varied from mostly 200 Kbps to occasionally 1000 kbps. Previously I would have a consistent 2500 to 3000 kbps (we are 3 miles from a country exchange). Ever the optimist I assumed this slow down was related to the switch over and assumed all would be well on changeover day. No such luck. BT service went live on Tuesday 26th, I connected the new Homehub 3, all the new cables and all new filters. BT set up CD established a connection but the speed problems remain. Now pages will not load, IE is just waiting for…, even Google home page just stalls. I have tried Ping-ing various sites and mostly these request time out. Broadband light is on on the homehub and the problem exists for 2 different computers, both on a wired network cable direct to the hub. For the record, I have tried with the router connected to the master socket to eliminate the house wiring and this makes no difference. I have started a dialogue with BT tech support (India), but they want me in front of the computer so that will have to wait until later. They say the line is OK on a line check. Stats from the home hub show last night the following: Line state: connected Connection time: 0 days, 00:06:46 Downstream: 3 Mbps Upstream: 448 Kbps VPI/VCI: 0/38 Type: PPPoA Modulation: G.992.1 Annex A Latency type: Interleaved Noise margin (Down/Up): 2.0 / 23 dB Line attenuation: 46.0 / 25.5 dB Output power 19.0 / 12.3 dBm FEC Events (Down/up): 8011538 / 994 CRC Events: 21079 / 1004 Los of framing (Local/remote): 0 / 0 Loss of signal: 0 / 0 Loss of power: 0 / 0 HEC Events (Down / up): 266231 / 768 Error seconds: 2014 / 1599 The high CRC and error seconds counts don’t seem good and the low noise margin is also worrying. I appreciate this is a new conenction and there will be a training period, but speed is currently non-existent and of course the problem was manifest BEFORE the switch to BT. Thanks in advance for any help, as I am posting from work I may not be able to check back and respond immediately.

Coming back with an update - something of a result actually. BT phoned, as promised bewteen 6 and 8 and admitted there was a fault on our line and they were working on it at the exchange. Speed is now up to 1094 kbps on the BT line test. BT say they are continusing to work on it and speed could vary until Monday when they will update me again.
For the record here are the latest router stats, looking better already, particularly the noise margin

Whats slowing down my page loading times?

So i've been plagued recently with a terrible connection that just won't seem to go away, and has been getting worse.
At first we thought it was the router in our building (out of our control) but apon talking to the other residents (in a floor below and above ours) they've been having no connection problems what so ever. I watched a guy open Google, and it sprang open no problem, no waiting time.
I've since reset my Airport to default factory settings (fearing i've changed a setting I didn't mean to) and created a new Ethernet connection with the default DHCP. I really don't think its an issue with my airport, because even when I plug the Cat 5 straight into my computer, it still loads slow/not at all.
Its not throughput, because i've ran several speed tests on speedtest.net (never failed me before) and both my husband and I are getting 47,000 kb/s download and varying between 400-1100 kb/s upload speeds.
With all of that in mind, we consistently get 403 forbidden, and DNS errors when trying to connect to pages that usually work fine, such as gmail, apple.com and google. Known working sites, and they won't work. If i open a lot of pages, eventually one out of 7 or 8 will work, and when that one works theres no issues with it.
I feel really out of my element, because I'm not sure if its a proxy issue or what, because i don't have a proxy. It seems to come and go, and no one else has issue with it in my building.
Sorry if this really doesn't belong here, but we don't know where else to go.
Note, i can't contact my ISP because I don't speak there language, and I can barely talk to my landlords...we live in Korea.
link to my speed test: http://www.speedtest.net/result/412690208.png

Update:
Apon attempting to check this very post, I got a 403 forbidden (quite ironic).
I tried a new setting I was thinking of playing around with, which is to change my Airport from being a Bridge, to setting up a DHCP with my husbands computer getting his own IP... Seems to be working a little better now, but if anyone has anything to input I would be very appreciative.

Copy the jdev_home/jlib/redist/uix2_install.zip file to
jdev_home/jdev/redist folder . It will overwrite an existing uix2_install.zip file.
Close and open the Jdeveloper IDE. It will prompt you for upgradation of projects. Press OK button in response.
Now you should be able to run the JSP pages.

EXTREMELY SLOW INTERNET WEB PAGE LOAD TIME

Does this happen with both Safari & Firefox?
What does DSL Reports...
http://www.dslreports.com/stest
report for both?
Have you cleared Caches in Safari?
What ISP is it?
Might try putting these in Network>TCP/IP>DNS Servers:

Blank Pages Load When Opening Facebook Notifications in Notification Center

When I get a notification in Mountain Lion from Facebook I am unable to see the page that should be loaded. All I get is a blank page but the url appears to be correct. This happens if I have logged out of my account in the browser. When I am logged in it takes me straight to the notification and I can see it without any issues. This has been happening only in the recent weeks. When I first started using Mountain Lion (since it was released) I would instead be send to the default page that displays the content but ask you to log into a account.

I came here looking for a way to disable those sounds; there's no way to do so in notification center. Even when I select "none," the notification center, the status still displays "badges and sounds," and all I want is the badges. Currently, the only way to do this is remove FB altogether from notification center, which pretty much defeats the whole purpose of the notification center in the first place.
The world is already noisy enough; the last thing I want or need is for my my computer to be making unnecessary sounds.

Really slow network performance in mavericks when you get into deep folder structure

So I've done the workarounds...
#/net
telling the finder not to write DS_Store files.
When connecting to a ReadyNAS on the network the speed is too slow. sometimes having to wait 30 mins for a folder to populate. I've noticed it's just when I get a few folders into the directory that it starts to slow up.
thing is... works fine from a PC running Win 7. And it works fine when I use a mac running mavericks but connecting to the same folder structure on an old windows server.
Any ideas???
I've even tried FTP but that didnt work either.

What is causing FF6.02 to have VERY slow and incomplete page loads

Every since I've upgraded to FF 5 [now running 6.02] on Win7, the browser loads extremely slowly on ALL pages and often [most of the time] just hangs and doesn't display all images. I can start Chrome, copy and paste the URL and have the full page completely loaded while FF is still incomplete.

Network Timeout error message when downloading iPhone iOS software in iTunes

When I try to download iOS 8.0.2 (or even when I tried to download iOS 8), I receive an error message telling me my network connection has timed out. I even tried troubleshooting by chatting with Apple support. Nothing they tried worked either. I eventually had to go to my neighbor's house and use her Mac and her wi-fi. Even that took a couple tries before she stopped receiving that error message too. I have the most up to date versions of my Mac software and iTunes. I've restarted the computer, my firewall is turned off, I've tried everything support says to do. Any suggestions? My iPhone periodically goes into recovery mode, and I'm afraid that the next time it does, I won't be able to recover it because I won't be able to download the iOS.

Same error (above).... again! I put my iPod into restore mode, but once again, it forces the update.

Delay in page loading when clicking on context URL's.

Whenever I click on a referenced URL, specifically in Outlook, it takes anywhere from 45 sec to 1 minute to load up. It goes to blank page and then pops up after a long wait. It appears to only occur to those URL's that have not previously been cached? A guess says that it is checking the website before caching it?? I've searched for a solution in every box and check mark I can think of. I must be missing a box checked or unchecked? I know I am overlooking something! Thanks for the help!

(1) Does it make any difference whether Firefox is already open or whether it needs to launch from scratch?
(2) Do you use any special startup procedures for Firefox (e.g., sandboxing software, the no-remote command line switch, etc.)?
(3) Could you check whether you have any "non-default" settings for the following preferences and test with the default settings.
(i) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(ii) In the filter box, type or paste '''tabs.load''' and pause while the list is filtered
(iii) If any of these appear in bold, you can double-click to reset them to default (or right-click and choose Reset):
* browser.tabs.loadDivertedInBackground (probably most relevant)
* browser.tabs.loadInBackground
* browser.tabs.loadBookmarksInBackground (probably not relevant)
You might need to exit and restart Firefox for this to take effect.
(4) Probably won't affect this issue one way or the other, but Firefox is now up to version 17.0.1, which includes some security fixes.
