[SOLVED] slow internet page loading problem (with tests)

Postby c_martini on Tue Feb 09, 2010 2:47 pm

On both my wired connection at the office and on my wireless connection at home (via router on 20mbps cable connection), I am experiencing slow internet browsing. This is not limited to one browser as I am using Firefox, Opera & Chrome. Local network file transfers seem fine. File transfers over the internet seem fine. The problem seems to occur in resolving http addresses. When an address is first entered into the address bar of the browser or when a link is followed from any page, there is a delay. I have done some tests and oddly it seems that performance is generally better with ipv6 enabled for some reason.

Asus Laptop: m51se
integrated wired adapter: Atheros L1 gigabit ethernet adapter
integrated wireless adapter: Intel Pro Wireless 4965 AGN


*** wired ethernet Linux Mint 8 ***

on my office connection with ipv6 disabled:

ping google: 55ms

Testing with Chrome: google's url on an empty cache, results in a 17 second delay before the page loads.
Testing with Opera: google's url on an empty cache, results in a 10 second delay before the page loads.
Testing with Firefox: google's url on an empty cache, results in a 12 second delay before the page loads.

on my office connection with ipv6 enabled:

ping google: 60ms

Testing with Chrome: google's url on an empty cache, results in a 8 second delay before the page loads.
Testing with Opera: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Firefox: google's url on an empty cache, results in a 4 second delay before the page loads.


*** wired ethernet Windows 7 ***

on my office connection with ipv6 disabled:

ping google: 55ms

Testing with Chrome: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Opera: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Firefox: google's url on an empty cache, results in a 1 second delay before the page loads.

on my office connection with ipv6 enabled:

ping google: 60ms

Testing with Chrome: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Opera: google's url on an empty cache, results in a 2 second delay before the page loads.

*** wireless ethernet in Linux Mint 8 ***

on my office connection with ipv6 disabled:

Testing with Chrome: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Opera: google's url on an empty cache, results in a 5 second delay before the page loads.

on my office connection with ipv6 enabled:

Testing with Chrome: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Opera: google's url on an empty cache, results in a 5 second delay before the page loads.

Testing with Opera: google's url on an empty cache, results in a 2 second delay before the page loads.
Testing with Firefox: google's url on an empty cache, results in a 2 second delay before the page loads.

If anyone can shed some light on a possible solution, I would greatly appreciate it... :?:

OK, more context. more data on your hardware

Sounds like (the delay that is for an http addresss) might be your system, in general, as all the icmp replies you have are 55-60ms, which is an insignificant
    Might also be useful to know your LAN/router setup connections, and if you are using any special software operations, like ICS (windows) or bridging(router )

      If none of the above, to me, looks like..
      • Insufficient RAM
      • Insufficient browser cache
      • Too many applications running concurrently
        --check with system monitor in mint (Gnome desktop edition)

    Thanks for your reply DrHu, however, I don't think it is my system as I have much faster performance in Windows 7 on the same machine (see tests above)...

    The laptop has 4gb. I think this should be sufficient :wink:

  • All browsers have their cache's on default values. Nothing has been altered.

  • At the time of these tests, there was no other apps running which actively used the network connection



    Thanks for those links. Again, I reiterate there are no issues browsing in Windows 7. However, I have changed the MTU setting to 1492 in Mint 8 manually for my wireless connection for home. This appears to have fixed the problem :D
