Slow browsing speed in IE7

Vejay · 03-23-2007, 03:26 PM

SYMPTOMS:

Slow browsing speed in IE7 or Mozilla Firefox using a hi-speed broadband connection
It takes 10 to 15 minutes for a webpage to load

CAUSE:

A known bug in Vista's TCP stack has not been fixed for RTM. The network throughput suffers immensely for Vista machines when Stateful Packet Inspection (SPI) feature of the certain firewalls is enabled. This is due to the new ‘autotuning’ feature of the TCP stack in Vista.

RESOLUTION ONE:

There is a workaround for this:

1. Click ‘Start’, type Run, Press ‘Ctrl + Shift + Enter’ key to elevate using Administrator privileges, equivalent to ‘Run as Administrator’
2. Agree to the UAC
3. Type ‘netsh int tcp set global autotuninglevel=disable’ and Press ‘Enter’
4. This will give a message ‘Ok’.
5. Reboot the computer and try browsing website.

RESOLUTION TWO:

1. Download Mozilla Firefox and install the same, since this neither worked in IE7 or IE6.
2. In the address bar type about:config, and Press Enter
3. In the filter bar type network.http, this will filter your search
4. Find network.http.pipelining, Right click on that and click on Toggle to enable it.
5. Find network.http.proxy.pipelining, Right click on that and click on Toggle to enable it.
6. Find network.http.pipelining.maxrequests, Right click on that and click on Modify, Change the default value to a max of 30.
7. Lastly Right click anywhere and select New -> Integer. Name it nglayout.initialpaint.delay and set its value to 0 - Zero.
8. Close the browser and restart the computer.
9. Then try browsing to a website using either IE7 or Mozilla Firefox.

Note: These settings are for the Connection and not the browser.

RESOLUTION THREE: (XP Only)

1. Click Start -> Run -> gpedit.msc
2. Expand Local Computer Policy -> Computer Configuration -> Administrative Templates -> Network -> QoS Packet scheduling -> Limit Reservable Bandwidth.
3. Double Click on it, Select Enabled, Set bandwidth limit to 0 – Zero.
4. Click Apply, Ok, close gpedit.msc and restart the computer.
5. Check for the browsing speed now.
