Windows 8 Flaw in Windows 8 Causing Slow Web Browsing on Chrome, Firefox, IE?

A couple of weeks ago I installed Windows 8 (fresh install from scratch, not an update) on my computer. I do a lot of web browsing and over the last couple of weeks I've been using Windows 8, I could swear the web browsing wasn't as fast at it used to be on Windows 7.

I then noticed I was having major issues bringing up my router's control panel (ASUS RT-N56U) so thinking it was my router I upgraded the firmware. Turned out, the Avast Anti-Virus I was running has issues with Windows 8. I removed AVAST and turned on Windows Defender (which in Windows 8 is also an anti-virus program now referred to MSE - Miscrosoft Security Essentials). MSE has gotten fairly good reviews so I decided to use it, for maximum compatibility with Windows 8.

However, although the router control panel would now come up okay, browsing still seemed to not be quite as fast as it used to be. I sat down at the old 5-year old Dell Desktop next to me that is running Windows 7, both computers were connected to the router via Gigabit Ethernet. I tested network speeds with to make sure they were both getting the same Internet speeds (which they were.) I found a couple 'heavy' web pages to test: Recipes, Menus, Cooking Articles & Food Guides (home page) (home page)

The browsing was MUCH faster on the Windows 7 machine!! So I decided to do more of a controlled test.

The Samsung Notebook is a Series 6 Core i5 with 6GB RAM and 64GB SSD running Win 8 Pro 64-bit. Windows Experience score of 5.9. Windows Defender (MSE) Anti-Virus. Windows Firewall Turned OFF!

The Dell Desktop is Intel Q8200 with 6GB RAM and a 5400RPM HD running Win 7 32-bit (not sure why 64-bit didn't install, sort of strange but oh well). It had a Windows Experience score of 3.6. Avast Anti-Virus. Windows Firewall turned OFF. Windows Defender turned OFF.

I went into Windows Task Manager on both computers and ended most if not all tasks that were not critical to the system and no other programs except the browsers were running.

I removed all plug-ins and add-ons from Chrome except the Page Load Time extension plug-in which can be downloaded here:

I also tested on FireFox using this add-on:

On the Windows 8 Machine I also tested with Internet Explorer 10 - unfortunately I couldn't find a page load speed monitor for it that would work so I could only do an informal visual+verbal count, stopping when I saw the page stop X in the URL bar change to the reload symbol indicating the page had completed loading.

On both test pages I refreshed the pages at least 10 times and averaged the scores. I looked at the page load speed monitor result but I also did a visual+verbal count out loud until I saw the page stopped loading objects.

The results were astounding (and very frustrating/disappointing because otherwise I really like Windows 8 as the OS in general seems better/faster than Windows 7 for multitasking)

Here's the results:

Windows 8 + Fast Machine + Chrome 23.0.1271.95 m on ~ 3.5 sec load counter / ~ 5.5 sec visual/verbal count

Windows 7 + Slow Machine + Chrome 23.0.1271.95 m on ~ 2 sec avg / ~ 3.5 sec avg visual/verbal count

Windows 8 Fast machine + Chrome on 5 sec avg / 5 sec avg

Windows 7 Slow machine + Chrome on 2.5 sec / 3 sec

Windows 8 Fast machine + FireFox on epicurious com: 4.5 sec / 4.5 sec

Windows 7 Slow machine + Firefox on 2.5 sec / 3 sec

Windows 8 Fast machine + FireFox on com: 5.25 sec / 5 sec

Windows 7 Slow machine + Firefox on 2.5 sec / 3 sec

Windows 8 Fast machine + Internet Explorer 10 on ~ 5 sec visual/verbal count

Windows 8 Fast machine + Internet Explorer 10 on ~ 6 sec visual/verbal count

(I didn't bother testing IE 10 on the Win 7 machine)

It is clear, that something in Windows 8 is causing the browsers to load web pages 30-50% slower. If you have a very fast Internet connection (like me - 35 mbit/s download and 6 mbit/s upload) in regular use, the difference may not be that noticeable to the "casual user" as the difference between as a 3 sec and a 5 sec page load speed are both fairly fast for these two sites.

But it you have many sites open at once and are multi-tasking and clicking lots of links hours at a time, it IS noticeable. Downright depressing when you compare it to a Windows 7 machine especially considering the specs on the Win 8 machine are much better hardware wise! If anything the Windows 8 machines should be faster.

Now I know a some people are going to be skeptical about my findings or give suggestions as to something that may be wrong with my particular PC. Obviously every PC is different, having different configurations, apps loaded, processes running, etc. But in my 25+ years in the Tech Industry my gut is telling me there's something not right with Windows 8 and it is just a matter of time until enough people complain to Microsoft about it to get their attention to find the cause of the issue and fix it.


* I tried the tests on Windows 8 with Windows Defender (MSE) turned OFF, Firewall turned OFF. No anti-virus programs running. IT MADE NO DIFFERENCE.

** I made sure the drivers for both my Ethernet and Wi-Fi Networking were the latest drivers. They are the on-board Intel 82579M Gigabit Ethernet and Centrino 6230 Wireless.

*** Running the tests on Wifi instead of Ethernet ALSO MADE NO DIFFERENCE.

The facts seem to point to something in the Windows 8 Operating System is slowing things down. I wish I knew what it was as I feel so frustrated that this new powerful Samsung Core i5 notebook running Windows 8 has slower web browsing than than 5-year old Windows 7 Dell Desktop sitting across from me.

I have seen many other posts about Chrome running slowly on Windows 8. It isn't just Chrome!

*** I would encourage others to run these tests as I would at least like to be 99% confident that I don't have some hardware or driver issue. ***

It sounds like you have put in a lot of effort to analyze and troubleshoot the web browsing speed differences between Windows 8 and Windows 7 on your machines. The tests you performed with different browsers and configurations provide valuable insight into the potential performance issues you're experiencing.

Here are a few things to consider and possible steps you can take to further investigate and address the speed differences:

1. Browser Optimization:
- Sometimes browser extensions or settings can affect performance. Ensure that your browsers are up to date and without unnecessary extensions that might impact speed.
- Try resetting your browser settings to default or test browsing speed in incognito/private mode to rule out any extension-related issues.

2. Network Configuration:
- Ensure that your network settings are optimized. Check for any background activities that might be consuming bandwidth.
- Test different browsers on both machines to see if the issue persists across all browsers.

3. Windows 8 Optimizations:
- Check for any Windows 8 updates, as Microsoft often releases updates to improve performance and stability.
- Consider checking the Task Manager to monitor system resource usage while browsing to identify any potential resource-heavy processes.

4. Additional Tips:
- Clear browser cache and cookies to ensure optimal browsing performance.
- Check for any background processes on the Windows 8 machine that might be consuming resources unnecessarily.
- Consider performing a system maintenance task to optimize the overall system performance.

Running these additional tests and optimizations may help in identifying the root cause of the slower web browsing speed on Windows 8 compared to Windows 7. Since you have already ruled out hardware and driver issues, focusing on software configurations and browser settings could help in resolving the speed differences you are experiencing.
