Some websites are loading real slow

[putty]

Hey guys,

lately I have been having a real annoying problem with some websites loading real slow on my PC, and only on my main pc, not on my laptop or tablet.

Some info:

(Its a Mac, I know)

OS: OS X 10.8 Mountain Lion(It isn't a problem of this new OS, I also had the same problem when I was still on Lion)
Network: 20mbit ADSL, and connected with a cable, I get good speeds with it(around 1.8mbps)
Router: The default router that I got with this ISP, it doesn't allow for much configurations sadly.
Browser: Google Chrome, but this issue is with all browsers on this pc

Now a really weird thing that I just noticed today:

When I am connected both with WIFI and with the ethernet cable, load up the website and then disable one of the two connections(WIFI or ethernet cable) the website loads up almost instantaniously.

EDIT: even weirder, it also works when I am just connection through ethernet cable, load up the site, unplug the ethernet cable(So I loose all internet connections), Site loads up perfectly...

I really hope you guys can help, because one of the websites that load so slowly is a website that I really need to access often.

Anyone?

Check you are using the same DNS.

[putty]

Same DNS as what?

[Mufflore]

You have 2 machines.
Check they are both using the same DNS.
If not, change the slow one to the fast one.

[putty]

They are both using the same DNS

[Mufflore]

Open a command prompt and do a tracert to the website you are loading on both machines.

ie
c:>\tracert www.microsoft.com

Copy the text response and paste it here.
(right click the screen, select mark.
select the text you want, it will highlight, press enter.
text is now in the paste buffer)

Don't forget I use a mac!

I did a trace

this is what it gave me:

I should also add, that I had this exact problem when I used this PC on another network(different ISP, IP, DNS, etc)

[Mufflore]

Oh yeah

I need the tracert from both machines.

If your IP is on the screen, pls remove it.

Trace from the other pc

[putty]

But www.microsoft.com is not a slow loading webpage on either pc's, so I don't know how usefull this could be

if you want I can do a trace to a slow loading website?

[putty]

My bad, it was just an example

Here is the slow one:

Too me it seems it in pinging perfectly though...

[putty]

Okay a big update here:

I used firebug and the chrome network tool to see what element the browser seems to hang at while loading the site.

It seems it can not load this:

js_visitor_settings.php
dev.visualwebsiteoptimizer.com/deploy

This apparently causes a major timeout on this pc... Anyway to circumvent this file?

[Mufflore]

On the slow machine, does it always time out on line 7, while on the fast machine does it always report back 3 times?

caught your edit.
Did you run it more than once to see if it stops at the exact same point?
Does it only happen on certain websites?

[putty]

No I tried it a few times, it times out only a few times, also only a few times on the slow loading machine.

Anything on that

js_visitor_settings.php
dev.visualwebsiteoptimizer.com/deploy

[Mufflore]

That may be a red herring if it happens on both machines, it looks like the server on line 7 is having a bad day.
When it does respond its quick enough.

It doesnt explain a general slowness on one machine though.

Is the network interface in the slow machine a 10Mbit one?
If not, is it configured to use 10Mbit or single duplex?

[putty]

to clearify, they are both fast/modern pc's, so the "slow" pc is the one that is loading some websites slowly.

They are both on a 100Mbit, or 54Mbit wifi, which gives no difference.

But I found the issue... It is that single file that I was telling you about, I turned off Javascript in firefox and the website loaded up very fast.

So as a "fix" I added a blockage of javascript to that certain website with Chrome, now the page loads very quick, except that some dropdown menu's look a little bit off(which isn't weird if they are using javascript)

Thanks for your help though! This had been bugging me for months!

[Mufflore]

Well done.
Does it help other websites you had trouble with though?

[putty]

Well, I can't for the life of me remember what other websites loaded so slowly for me

[Dude111]

I have noticed slightly slower loading also on alot of sites the last few days.....
