all browsers are slow


I'm trying to make the switch to a linux os. I love so many things about the distros I have tried. First Ubuntu and now Slackware 11. One common issue that I have had is the internet browser. Both distros surf the net at a snails pace reguardless of internet browser. I have tried installing onto different computers so I know the problem lies some where els. I hope the information that I provide can help lead to a solution. I also will be willing to read any books that may help lead to a solution so feel free to recommend materials. I am reading the slackbook currently and I have the Linux Bible 2005 version.

If any other information could help lead to a solution I would love to supply it. I want to convince my friends that I'm not wasting my time with linux. I have spent hours browsing and searching for answers. I hope that some day I can help others to solve their troubles so that I can give something back.

Also I connect via a Linksys rtp300 broadband router with roadrunner highspeed internet. One other Windows xp computer connects via the same router and no its not stealing all the bandwith even when its off my browsers are slow.

it looks like you IPv6 on. turn it off. It will vary by distro type.

Also try and set the DNS servers to the ones our router is using. Somewhere in your router's config screens should be a couple of entries like nameserver:255.255.255.0 (enter real # here)

it can slow things down in Linux to have it search the router and then the internet for DNS entries.

Hey Slack guys: a little help in the locations for these?

I have tried the Ipv6 solution, on ubuntu there is no, or very little difference. On Slackware it is the same. I will try the name server suggestion. Thankyou.

I set the dns server up and I'm still so slow. any suggestions will be considered. I've noticed that I'm not alone on this issue. There must be a good how to on this subject somewhere. It must be a configuration issue.

It may not be a configuration issue. I had some very bizarre performance problems with my browsers and it happened that on Win they ran fine. After checking every possible difference I called my ISP who swore up and down that they weren't traffic shaping. I suspect they were. I used their web proxy and then I got my rated speed. After a few months everything started working normally without it.

I can't explain it other than that they were throttling non-bloze endpoints, as I tested this on several Slackware machines on different boxes, different NICs, with a router, without a router, with OpenBSD, etc.

did you setup the machine as a dns server or did you add your ISP's dns servers to your config file? I'm sorry if there was any confusion on my part. Try and add your ISP dns servers (obtained from your router and/or ISP website)to your /etc/resolv.conf ("nameserver=xxx.xxx.xxx.xxx").

When I open the /etc/resolv.conf I find 4 dns servers two are also found in the router the other two I don't know where they come from. Could they be causing the trouble?

To check out Randux' suggestion, do you have the option of installing on a laptop and checking the same config at home and at a friends house?

frustrated

I reinstalled, because I guess I just wanted to check something out. I'm new to slackware so I'm experimenting a little. I'm now running the old 2.4.33.3 kernel and I've got acceptable speed back in my browser. All would be great if I could mount my usb devices. After some goggling I found this not to be an uncommon problem with this kernel. So I'd like to install a kernel that would take care of both problems. Can any one help with this and or how are folks doing with the 2.6.19 kernel. Any good "how to" on compiling your own. I'm all ears folks. I just want to get this right.

There's a howto here at linuxquestions: http://www.linuxquestions.org/linux/...d_Symbol_HOWTO. Also the readme files (or was that install files?) that come with the kernel have good descriptions of what to do. Be prepared to spend some time on this though, it takes a while to go through all the options If there's an option you don't know what to do with (yes, no or module) the defaults usually work fine. Or if you're unsure if you really need it, put it as a module.

Btw, I don't know if slackware have an easier way of installing kernels, but then I guess someone else will tell you...

One more thing. I haven't compiled a kernel in a while, but it's probably still a good idea to have a list of your hardware and what linux drivers work with it. (E.g. for your network card).

http://rkrishna.tp.googlepages.com/slackerbasics#26ker

pulled from a thread here this Slackware forum.

I *made it* in the past (after some failures) it's exhilarating to be successful.

Um I snagged the above as a reminder/reference for myself (I later went to do it again and couldn't remember what I'd formerly done that had made for the success)

but one huge impression is use of say Patrick's config file as a base from which to start (oldconfig or the likes then makemenuconfig or whatever using mentioned config as a base.

Once *base* then only need to *add* to that base what I specifically need and also to remove/take_away unneeded items in the config.

the config is such huge that i found it too overwhelming thus always blew it when started from scratch config. Likely I'll not do it now unless I'm using a config as my base config from which to add and/or subtract (add or remove things).

P.S. my outdated Slack current 2.6 www browser is intermittently (albeit too often) way too slow.

In Konqueror www browser (site specific only) I changed the reported browser string to MS Windows XP with MSIE

This sped it up only on those sites that I so specified.

Also I've a Qemu virtual machine with Windows 2000 in it and it's virtually networked to Slack and my internet gateway. The latest Firefox www browser running on Win 2K in this virtual machine *browses the www fast*. There's no comparison -- like lightning this Win www browser -- at a snail's pace the Konqueror browser directly on the host OS which is Slack.

downloads are *very* fast (at the max speed of my DSL) either via web browser or wget on Slack.

Prob is with only http www browsing on (now recently outdated current) Slack but not on the guest OS running in Qemu.

With regard to your original problem, can you post your resolv.conf? This could quite possibly be the trouble. Also, what kind of router and internet connection do you have? Some DSL Modem/Routers set bad information in your resolv.conf.

With regard to installing 2.6.x kernel, try the packages in Slackware's /extra packages. Do read the readmes first, but it is quick and straight-forward. If you really want to do it on your own, use Slackware's config file as a base to modify. You just might appreciate having a working system, though, before tackling your first kernel compile.
