Software - ipv6 disable

Post subject: ipv6 disable
How can I set my network manager to ignore ipv6. It slows down loading mzilla apps.

I have WICD installed which works nicely for me http://aptosid.com/index.php?name=PNphpBB2&file=viewtopic&t=382&highlight=

Netwirk Manager has a drop down for ipv6 "ignore", "automatic" etc.

Ceni doesn't have any option regarding ipv6.

EDIT

I used an ubuntu hack described here http://www.techairlines.com/2010/10/03/disable-ipv6-on-ubuntu-to-speed-up-browsing/ to turn off ipv6 system wide.

Before anyone yells at me for posting it, let me state that I am not offering this as a solution to the slow startup problem with mozilla browsers. Especially since it didn't help speed up Iceweasel or Firefox-Aurora that much.

Wow over 100 views and no responses.

I guess I did answer my own question.

So let me ask this, How do I speed up loading network apps?

Iceweasel takes about 15 seconds from the time I click its icon to open.

Xfce4-weather-plugin has to be refreshed 3 times before it accesses data.

Having used the "U" word, this thread is probably headed for the Dragons Dept. anyway, so I'll share this old, but still valid info.

There may be other things that you can do -- try turning off desktop effects, for example. If you post the output of

      Code:
infobash -v3


to show your hardware and installed system, it might give further hints.

We do not ship or recommend network-manager, so most of us will also not use it - that's the reason for no answers. Have a look at Ceni, which is our own network tool in Aptosid, and the supported one.
Greetings,

Noone commented because everyone has ipv6 disabled expect you and their internet is therefore so blazing fast that millions of pages are flickering over their screens in a split second, so your question was overlooked…

If it's just mozilla apps, have a look at the config option: network.dns.disableIPv6
But note what the description says: http://kb.mozillazine.org/Network.dns.disableIPv6
Especially the "Some suggest that setting this preference to true on any OS will speed up connections, though this is probably a placebo effect."

Less than 1 second for me, ipv6 is not disabled in Iceweasel.

IPv6 support is not a bug, but a necessity.

If you experience problems with IPv6, some gear between your system (aptosid is IPv6 capable, as are modern versions of Windows and OSX) is simply broken (most likely your router) and in need of replacement (a firmware upgrade may fix this). There is no problem if your router can't do IPv6 yet, but it mustn't fail to properly reject IPv6 operations then, rather than claiming to support it, while actually failing to actually deliver.

Wow, thanks for all the responses guys. I'll try to acknowledge them all in this post.

As I mentioned in my original post, "Ceni doesn't have any option regarding ipv6" so I tried Ceni but it didn't do anything for me. Am I to understand that other network managers, though in the repository, are not supported if they do not ship with the OS?

I have ipv6 disabled in all my browsers and it does make a difference in responsiveness once the browsers are opened. This "fix" was also mentioned in the ubuntu hack that I referred to in my original post.

I boot 2 other OS's, Arch and openSUSE. On my Arch installation my network is "so blazing fast that millions of pages are flickering over my screen in a split second" My openSUSE network speed is somewhere in between Arch and Aptosid.

Edit

I timed openSUSE and it is actually slower the Aptosid:

Firefox took 18 seconds to start up.




My post here is about start up time. I have used network manager on other OS's and set the ipv6 option from "automatic" to "ignore" and sped the start up time considerably.

I was hoping to find a solution here that does the same thing network manager does with the ipv6 option, without actually installing network manager, because I do like it either.

My Internet Service Provider does not offer ipv6. My router doesn't support ipv6 and its the same router that I use when starting up Firefox in less than 1 second on Arch.

I have to respond to this post separately. I have gotten responses like this many times in many forums. I try to tell myself that they are offering encouragement, "see I did it, so it is possible".

I can't help think that you're saying " don't blame the OS, because it works for me and therefore the problem must be with you."

If this is true, then let me say that your response is not helpful in any way and may I suggest not responding at all if that is all you have to say.

You can interpret my reply any way you want, I was just illustrating that enabled ipv6 has no affect on Iceweasel start up times for me. And no worries about me replying to any of your future posts, I won't be.

I suppose that it would be hard to see any difference in Iceweasel start up time for you with ipv6 disabled.

I always wonder why you get that one last spam email after unsubscribing. It must be a "last word" thing.

That's my take on that…

In reality, maybe different iceweasel versions (claim to) have different startup times, newer is usually faster (but not always). Different extension (versions) and other setups can affect startup, too. At startup, files are loaded from harddisk, not from the internet…

So measure startup-time is hard - you always need to start from a cold-cache, which means remove from RAM cache, kill all temp/cache files, … Claiming that an oven you used ten seconds ago at a heat of 200°C is faster at 210°C than a oven you haven't used in a year and stored in a big fridge isn't that surprising…

So you're saying that without cleaning out the cache, that my browser should start faster than with the cache empty.

It still takes too long. I have tried Iceweasel 8.0, Firefox-Aurora 10.0, Midori 0.4.2 and Chromium 15.0. Both mozilla browsers took 15 seconds while the webkit based midori and chromium took less than 1 second.

Maybe its the gecko engine or xulrunner slowing down the mozilla browsers.

IMHO iceweasel/firefox has been slow since after phoenix, phoenix kicked ass.

I am running
      Code:
Mozilla/5.0 (X11; Linux x86_64; rv:12.0a1) Gecko/20111223 Firefox/12.0a1 ID:20111223032107
at the moment, I have no problems with speed, addons, themes (at least the ones I normally use)

I remember Phoenix rising from the ashes of Netscape and becoming Firebird. Did you run it on linux?

I'm now using Google Chrome 16.0.912.63, Icecat 7.0.1-0precise1 and Dillo 3.0.2-1. Dillo's the fastest GUI browser in the world. Chrome's pretty fast, so is Icecat, but it still takes 15 seconds to start.

Extensions take time to initialize as well so the fastest you can get is in safe-mode or a bare profile that has no extensions installed.

yeah, but 15 seconds? and it it took that long the very first time I started it.

did you start it with the default profile or the one you have set up with your extensions and such

I generally create a profile for my daily browsing needs while leaving the default profile as a fallback

tried
      Code:
icecat --profilemanager

and created the "Default User" profile then clicked "Start Gnu Icecat"
after 15 seconds it started to load, 15 seconds after it started it loaded for a total of 30 seconds.

BTW Merry Christmas

Something's wrong, don't know what; the only information I've to offer is that it takes mere seconds to start up Iceweasel here and get the default homepage (currently Google.com over https) to load. It would be (a little) nice perhaps if I could point you to an existing bug and a message from the devs that they're taking care of it but it seems it's something with your system alone.

You can disable IPv6 for Iceweasel/Firefox through the method in DonKult's first reply but I doubt it will make a noticeable difference, let alone shave off 10 seconds or more. I think Iceweasel's start-up should be acceptable by default on any system without optimization and your start-up times don't really qualify as acceptable here imho.

Starting Iceweasel has something to do with the speed of the storage (hard disk), memory (amount free & speed), video driver. When there was an unfortunate change in the xorg recently, it made my desktop apps slower to start too. Are your complaints exclusively about the responsiveness of Firefox or is it a general issue? Have you tried changing video driver, freeing up memory? Does dmesg show errors?

I understand Arch behave as it should and it runs on the same hardware. Things to try: hook up your system via a cable to determine if the problem sits in the wireless. Boot into Arch and ping a few websites, do the same with aptosid and see whether Iceweasel has anything to do with the issue or if it's a general networking problem.

I ran dmesg an attatched the konsole output.

I always start with a blank page. I don't have any proprietary video drivers installed and I have "nomodeset" in my kernel options.

Chrome, Dillo and Konqueror start very quickly. It just seems to be the gecko engine browser that take a long time to start.

Did you use your .mozilla from another distro ?

If you really want to figure this out
      Code:
apt-get remove --purge iceweasel


remove the .mozilla folder in your home (back it up first)

      Code:
apt-get install iceweasel

open it once and close it, then reopen it, keep it naked (no addons, themes, etc ...)

Is it still slow ?

If not install addons, themes one at a time (closing and restarting iceweasel after each install

I have to agree with CaesarTjalbo "Something's wrong, don't know what"

all my distro's (all debian) iceweasel runs fine (except my main box which runs firefox nightly 12.0a1)

I have finally got iceweasel startup time down to less than 1 second. I reinstalled my OS. This time I didn't install any other browsers besides iceweasel and seems to start right up immediately. Could it have something to do with checking to see if it is the default browser?
