Internet Explorer 11 Slow Performance

A few users have noticed that “Find and fix problems with Internet Explorer performance” link no longer exists on Microsoft’s support page. Soon after that, Microsoft dropped support on this page for easy fix solutions.

You can find support to fix Internet Explorer issues in the articles and guides below:

Many early testers of Windows 10 have been complaining that Internet Explorer is rather slow for them, as a couple of forum posts have surfaced at the time of release. As a reminder, if you didn’t know, Windows 10 Technical Preview came with the same Internet Explorer 11 version as in Windows 8.1, but it did sport some improvements.

Windows 10 users have used the Feedback app in Windows 10 TP build 9860 to complain about the existing Internet Explorer version. Here’s what one of them has been saying:

“Can’t say why. Page loading super slow. Even already visited pages opened in new tab”

Some have been saying that the Internet Explorer 11 browser also crashes all of a sudden, does not show all letters after an update, does not display web pages correctly, and performance with JavaScript is really slow.

Why is Internet Explorer slow?

Internet Explorer 11 has aimed to be the first browser to make Internet connections more secure and reliable by reducing the use of vulnerable ciphersuites (ex. RC4) and by using the latest security standards, TLS 1.2, by default.

All intentions are good, but the facts are still showing that users complain about:

  • internet explorer 11 slow to launch
  • internet explorer 11 slow loading pages
  • internet explorer 11 slow javascript performance
  • internet explorer 11 slow and not responding
  • internet explorer 11 slow opening tabs

One reason might be that many web pages are not officially supporting Internet Explorer anymore. Internet Explorer 11 is hardly being maintained and merely used for Intranet websites and apps that require ActiveX controls.

Some users consider that the TLS 1.2 is actually causing IE 12 to work slow, but secured. By any means, if you enjoy IE 11 and want to make it work on your device, check out the following tips and fixes to apply now.

How to speed up your Internet Explorer

Clear IE Cache regularly

The first thing you can do is to clear Internet Explorer Cache. You can do that from browser‘s Settings following the steps below, or with some third-party cleaning tool, like Advanced System Care or CCleaner.

  • Launch Internet Explorer 11
  • On the right-hand side of the browser, click on the gear icon – the Tools icon
  • Go to Safety and select Delete Browsing History
  • Uncheck all options except the Temporary Internet files and website files
  • Click the “Delete” button.
  • The Delete Browsing History window will disappear and your mouse icon might go busy for a while.

Bonus Tip: Set cache size at 200-250 MB. A larger cache won’t speed up browsing. Internet Options> General tab> Browsing History> Settings> Disk space to use.

Disable Add-ons

  • Open Internet Explorer and select the Tools button
  • Click on Manage add-ons
    How to disable Add-ons in Internet Explorer 11

  • Select each add-on that you want to remove and click on Disable.

Scan your system for errors

Reset IE to default level

Finally, go to Internet Explorer, click Tools > Internet Options > Security > Reset all Zones to Default level.

These tweaks should help you fix your slow Internet Explorer and improve your browsing experience.
