Slow web page loads on Mac, but not for PC

I use a D-Link wireless router (DI-524) for my PowerBook G4 15" and my roommate's Dell PC. Very recently I seem to get very slow web page loads with some pages not even loading at all.
Airport is consistently connected with no drops at all and when I'm downloading something it never gets interrupted the whole way through.
My roommate's PC has no problem whatsoever and all of the web pages that he visits load instantly. It seems that my main problem is with web pages.
I've tried doing a clean install on my Powerbook, I've tried resetting the router (I've tried upgrading the firmware but the router decided it didn't want to work with the new version). And surprisingly, I get the same slow speeds when I hook up my Powerbook to my router via ethernet cable. The only time my speeds are perfectly fine is when I hook up my Powerbook directly to the wall (I dorm in a university so we have a T3 line).
Can someone please give me some advice on this very frustrating issue?

In addition to Neds suggestions, empty the Safari cache (which should be empty after a clean install).
Goto the Safari Get Info screen (in Finder or in Dock if you have Safari there), click the triangle on languages, and disable those you don't use.
My Safari response time was significantly slowed after the 10.4.5 update, and using the combo updater took care of that. The 10.4.6 combo update is located here.

Slow Web Page Loading in Safari & Firefox

A few months ago, Safari began loading web pages extremely slowly, regardless of the Internet connection. I don’t recall doing anything special at the time; it just kind of started all of a sudden. I thought it might a problem with Safari, so I downloaded Firefox. Although Firefox was a bit faster at first, it quickly (over the course of about 1 week) slowed down as well. To reiterate, the browser application itself was loading quite rapidly, yet the web pages were taking a very long time. On average, it takes more than 90 seconds to load a web page as simple as Google.com. Before this problem began, a web page would usually take an average of about 15-20 seconds to load. I am sure that it is NOT due to my Internet connection because the problem remains regardless of whether I am at home (where I have a cable connection) or at work (where I know the Internet connection is very reliable). To further support this, my roommate who has a 4 year old Dell PC loads web pages using Internet Explorer significantly faster than I do (with my 2.5 year old MacBook Pro). I have not noticed any kind of performance decrease with any of my other software or hardware; the computer still starts-up quickly, and all of my other software applications are very responsive. Any suggestions on how I might fix this issue?

Before this problem began, a web page would usually take an average of about 15-20 seconds to load
I would call that slow! 1-5 seconds should be the maximum.
The following usually works on both Tiger and Leopard:
(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 / )
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.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.

W550s: slow web page loading - video problem?

My system:Thinkpad W550s with the 2880x1620 px Display.CPU: i7 - 5500URAM: 8 GBSystem: Win 7 64 bitDrives: system 256GB m.2 SSD This problem seems to be Lenovo video display, not the web browser or the internet connection: I see the same slugish page loading with Chrome and Firefox; I see the same problem with WiFi or wired ethernet. No other computers at my house have this problem. Specifically, I display Zillow in web browser. Choose a search option that displays hundreds of homes within the map. Zoom in or zoom out. Zillow redraws the entire map, and it is very slow on my W550s (sometimes 2 seconds or more). Other computers will refresh in a few blinks of the eye. I have not used the computer enough to say if I'm also seeing video display problems. There is a slow video on W550s topic in the forum, too.. I haven't yet tried some of the (unsuccssful) steps recommended there.

Occasionally I see it reach 100% when doing nothing but browsing! So what does that mean to you? The observed sluggishness seems very real, but I have a hard time quantifying it. My desktop system (older AMD CPU, 8 GB RAM, HD, not SSD) is definitely snappier. The graphics card on the desktop system is nothing special - some nVidia $50 card. Again, in the not quantifiable category, a friend recently brought an older Dell XPS laptop to my home that I had gifted to her. It is from 2007, runs Windows Vista (yikes!) and only has 4 GB RAM, yet it definitely felt faster with Firefox. It even seemed to load Firefox and IE quicker! This is really disheartening. I should load Adobe Lightroom on it and see how that runs.

Slow web page loading in Safari with DSL

I've got an intermittent problem which may not be Safari-related, but I need to ask it anyway because Mac friends of mine have experienced similar problems.
I just changed my ISP from satellite interenet to mid-speed DSL. Ever since the changeover, I've found that more often than not, pages seem to load about 66%, then data reception seems to stop. When pages DO load, they load quickly, but most of the time, pages seem to stop loading at a certain point. If I hit refresh (often after several times), then the page loads as fast as lightning.
Could there be something with Safari that interacts with the DSL connection which causes the loading to stall? Many times, pages don't load at all, and I'm wasting time waiting for pages to "just pop up", Other times, I will get "Page Not Found" even though I KNOW there's a page existing at that particular location, yet Safari doesn't display it unless I first hit "Refresh". Still other times, The same pages load just fine, whether or not I empty the cache and close the downloads window.
Any ideas, people?

Hi Jim,
The 'refresh to force the page to load' symptom is usually a sign that you either have the wrong DNS addresses specified in your Network preferences or your ISPs DNS server are very slow.
Have a search for DNS on the Safari forum - there's quite a few posts and sample addresses for you to try out.
Good luck.

Malformed packets - slow web page loading

I'm running bm3.9 sp2 with some post bm sp2 files as provided by Novell
support on a nw6.5 server.
I've noticed that on IE and Fireforx browsers, that web pages will often
take a long time to load and typically if I hit the 'stop' button on the
browser and do a 'reload' or 'refresh' for that web page, it will
immediately load fine.
I've been looking at the tcp stats but don't notice anything strange there.
I ran pktscan and the only thing standing out is about 200+ malformed
packets out of about 3000 packets. I've run pktscan a few different times on
different days and still noticing these malformed packets.
I was wondering if this could be a problem or any other suggestions on what
to look at.
TIA

correction on packet count - 200+ malformed out of 20k total packets
captured.

Slow web page loading

i have a linkysys modem and wrt150n router. i have one desk top and a laptop that uses the wireless connection. everything was working fine untill a couple of days ago. then webpages started loading slowly on the laptop. the signal strength is excellent. i do not know what happened to cause this problem. desktop webpages load quickly. can someone help.
Solved!
Go to Solution.

On the setup page of the router,under wireless tab...Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Under Advance Wireless tab...Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...Now,check the connection.
Also disable the firewall on the computer.Adjust the browser settings on the computer...Open an IE, click Tools >> Internet Options, then delete all files, cookies, history, forms...Goto "Connections", make sure Never Dial a Connection is checked, click on LAN Settings and make sure all the options are unchecked...Once you are done click on O.k...Close the IE and re-open it...

Web page centered...but not centered

I have a webpage I created that I wanted to be centered in the browser no matter what size the browser is. I succeeded with that, but for some reason, the left side of the page remains smaller than the right side of the page. Can anyone tell me why this may be and how to correct it? Thanks in advance.

WRT54GS - Web page loads slow or not at all

My parents have two wireless laptops accessing their WRT54GS. Both receive excellent signal strength. Web pages load at normal speed for the first unit to access the internet on their network. However, the web pages will take forever or not load at all for the second computer, despite the fact that the signal strength to the second computer remains excellent. It does not matter which connects first and which is second; the problem still occurs.
I might mention that the computers and the router were purchased on Dec. 23, so everything should be current, with the exception of the 12/28/06 firmware release for the router.
Any suggestions would be appreciated!

hi...you can try different wireless settings on the router...
channel -- 1,9 or 11
under advanced wireless settings ,
beacon interval - 75
frag threshold - 2304
RTS - 2304
if this does not make any difference then upgrading the firmware could help you....

My Internet Connection is Fast, but Web Pages load slowl

I have tested my connection on several websites. I am using RoadRunner and I consistently get speeds between 3500-4500 kbps. In the past few days I have the same internet speed but all my web pages load really slow. Up until this problem I would click on a link and it would take 2-3 seconds to load the next page. Now it is more like 15-20 seconds. Once I get a page loaded if I download something from that site it is still a fast download.
Any ideas on what could have slowed loading web pages , but download speed still shows really fast?
Your help is appreciated
Cheers
mrjazz

If your download speeds are still fast, it is most likely the broswer that is slow in rendering the pages.
Are you using Safari and if so, do you leave it open all the time? Safari is notorious for hogging RAM and CPU cycles and slowing to a crawl if you do not quit and restart it.

Web pages load SLOW on IPad: how to disable DNS prefetching; other ideas?

Brand new IPad 16 GB WiFi + brand new Airport Extreme in bridge mode. Comparing IPad web page load speeds with side-by-side WinXP computer running IE8. Any web site will do: take www.apple.com if you want.
Problem: IPad web pages generally load much too slowly compared to IE8 on a computer 6 inches away on the same Airport Extreme network. Maybe twice as slow at worst, occasionally not much slower, but generally pathetic and annoying. WiFi signal strength is "excellent". Airport Extreme network is working great with all my (Windows) computers and devices except the IPad.
I already switched to OpenDNS on my Airport Extreme; didn't help noticeably. I would like to try disabling DNS prefetching in Safari, but don't know how to do it on the IPad. Question #1: How do I disable DNS prefetching? Question #2: Any other suggestions for this embarrassing (to Apple) problem?

I'm experiencing a similar problem with a new iPad 2 using iOS 4.3.3 connected to the Internet via Time Machine to a DSL line. The Speedtest X HD App shows the connection speed to be fine (about .6 Mb / s). The problem is only with accessing web pages. I frequently get a "server not responding" msg. There is no problem when I connect the device via USB to an iMac, only through wifi. The iMac itself (Intel with OSX 10.6.7) periodically experiences problems (both Firefox and Safari): I have learned to solve it by cleaning out cache and fixing disk permissions periodically. I've tried cleaning out cache on the iPad, deleting cookies and erasing web history, but that doesn't seem to make any difference. The problem reminds me of an old VNC problem: you had to allocate a large amount of cache or streaming would stall. This is also happening with the iPad 2. Maybe the problem is a DNS channel issue but my impression is that it is somehow related to a memory or cache issue with the iOS device or to Airport. I've occassionally experienced similar slow page loading problems with other Airport connected devices--it varies from device to device. It seems to be a client-side software or caching problem.

Why is Web Page Auth on MAC Filter Failure not working on Anchor Controller?

Hi,
I have implemented a Guest WLAN solution as per the recommended design from Cisco. We have two internal WiSM2 controllers providing services for Internal secure SSIDs. Both these controllers are members of a Mobility and RF management group.
Two 5508 controllers have been installed in our DMZ for resilience and have been placed into a separate Mobility group. All controllers (internal and external) have been linked together as mobility neighbours in a full mesh and a new SSID for Web Guest traffic has been anchored to the controllers in the DMZ.
Web page authentication works perfectly fine, but I cannot for the life of me get the MAC filtering override to work, i.e. if a MAC address is present, do not redirect to the splash page for web auth.
I can get MAC auth working by iteself, but not with the Layer 3 option selected for web page auth on mac filter failure.
I know I can get around this by just creating two separate SSIDs. But the business is used to just having the one SSID for all guest traffic.
Is this a known limitation when anchoring SSIDs to controllers in the DMZ ?

Hi Nicolas,
I guess they changed their mind to add this fix in 7.0MR3. Now the fix will be in 7.2 release planned to be release in FEB.
There is a documentation bug opened to add this to configuration guide :

My MAC has gotten very slow. Pages load slowly. How do I fix this?

My MAC has gotten very slow. Pages load slowly. Multi colored disc appears on screen at times. (like the hour glass on PC's) Anyone know how to spped it up like it was new? , at times not at all.

Examine this comprehensive trouble shooting article:
https://discussions.apple.com/docs/DOC-3521
Usually the Hard Disk Drive is the problem area.
