Title: [XP PRO SP3] settings for a fiber connection (SDSL 50Mb)
Post by: chocka on December 27, 2008, 08:21:06 am
1. Download CableNut.

OK done.

2. What type of connection do you have?

I have a fiber connection

3. Who is your ISP and what is your advertised speed from them?

InterNLnet BV advertise with a speed of 50Mb up and down.

4. What are your current settings now?

I just give TCP Optimizer a try and it goes better, but do not know if there is an max to it because TCP Optimizer can only be used till 20Mb. So may be I need to double these settings?

After TCP Optimizer I get following results:

The tcp test is not a speed test but simply reports some hard coded settings on your computer.

Cablenut is looking for some settings from you while the other uses some pre-determined numbers.

Do some speed tests and report back...

Thanx for reply.

First I need to say that the change of the website looks great!!! My compliments.

1. A question: I read somewhere if the download speed is as same as upload the setting of DefaultSendWindow can be the same as DefaultReceiveWindow?

2. I saved the settings from mccoffee into registry, saved the setting as a ccs file as well and rebooted my PC.

3. And as chpalmer asked, I did some speedtests after point 2. And here are the results:

The info is as following Try; Ms; Downspeed; Upspeed (as the image shows you) and the action which I take in between of the tests. I thought may be they are in any influence of the tests. I used the tests from speedtest.net At the end I give an average; Max and minimal.

(http://www.speedtest.net/result/380883999.png) (http://www.speedtest.net)


Hopefully this give more info. So far I can not see from speedtest there are any positive changes?! Looking forward to your reply. Thanx in advance.

For a test I just rebooted my PC, turned of Firewall (PC tools v5.0.0.36) and Antivirus program (Antivir Premium) and started speedtest. To see there any diffs of those are not interrupting the speed of  my fiber  line.

(http://www.speedtest.net/result/380900489.png) (http://www.speedtest.net)

And if I see the results, I can only cry. These are not results I want see with a fiber connection of 50 Mb (advertised) up and down speed!!!?

Are you running xp x64 by any chance?     The reason i"m asking is maybe compound tcp might work better for you.


Are you sure that line isn't a shared line?  Also ar eyou using a router ?

Ok well your ping times looks great  the only other thing I could think of why you are slow is this.  Do you know how far you live from the central office ,or a remote terminal? the further away the slower you will be..    If no call the isp up they should be able to tell you

Also put your network card in 100 full duplex mode   Try turning the modem of for about 10mins see what happens aswell.   The link is a guide on how to change the duplex.   One last thing try reinstalling your network card drivers ,or see if there is a more current one at the manufacture's site.

Another item... Are you sure the DSL company has there equiptments WAN set to 100 instead of 10

Also
TcpUseRFC1122UrgentPointer = blank
DefaultTOSValue = 232

I didnt notice How far you are from the CO.. SDSL will drop off based on distance at least it use to.. On fiber I dont have that info. But it use to be that you didnt want SDSL over 8000 feet.
But personally I think the company needs to look closer at your setup in distance and the card your into at the CO.

Personally I wish I new more about "InterNLnet BV" and there policy.
Such as some policy's here will state that if the ping is low and your able to surf its based on the best connection you can get..
Also even if your on Fiber is it a shared connection at the CO similar to Cable. and or are you on a repeater to make it look like your close to the CO.

Please let us know if that changes in the settings helped some and what your Com[pany is doing about the speed and your distance.. Real intrested to find out
Thanks

These are my settings of the Intel Pro 1000 GT. So far I find, I use the latest last driver.

(http://i258.photobucket.com/albums/hh258/Chocka999/LinkSpeed.png)

There is also any difference to explain. I have a fibreglass connection, which means it is not shared like cable/dsl and there is no infleunce in distance from the central office like cable/dsl

I also tried your last settings, but I do not know what happend but after a reboot my PC was going very slow. Also tried to open speedtest.net, but after 2 minutes the website was still not opened. So I imported the first settings you advised and reboot again. But still no progres. Its only getting worse.

(http://www.speedtest.net/result/382155924.png) (http://www.speedtest.net)

@Dannjr, sorry for the confusion, but have no SDSL. It is a fibreglass connection with the same downloadspeed as uploadspeed. So like SDSL. I live in the Netherlands. May be this gives you more info http://www.reggefiber.nl/Default.aspx?pageID=40

untill Dan signs back give thease a shot odd though never heard of the fiberglass medium or atleast where the distance to the c.o. ,or rt isn't a factor the lines will have meet somewhere to get ont he isp's servers odd.

Like the saying goes you learn something new everday.

Results of the last settings:

using internet, like this site is very fast. But to open speedtest, it takes some time and the results of speedtest are to cry.

try testing at local sites   then  i'm kinda wondering if it's a distance betwen you and the  test is what is throwing us off..

Try these settings I think your downloads and surfing will at least balance out well with these and if the ISP is running there own TOS at least you'll be a step ahead of the game..

A few years back I had the fortune of helping someone that has a Fiber line in Japan.
its allot like DSL only over fiber with a 1500 MTU
The problem we found was a fiber relay between his home and the ISP where he went up to the web. The Relay cut the speed he was supposed to get in half.
It took him making several phone calls before he finally got a Tech to admit there was a relay on the line.
The Relay can be used to double the distance to and from the ISP allowing them to get more sales. and more connections sold.
I could get into this real deep but unfortunatly it might take a lifetime..

My suggestion is try the above settings. With the reboot of course
Then find a Fast server with at least a 8 to 10 meg download to test on near or closer to home.
I tryed the speedtest.net site this morning on a 6 Mb connection and it was off by 1Mb
There has to be some fast servers in Germany you can test off of like say finding a download on the AGFA website

So far no succes at all

What i've done today. cleaned PC in safemode. un-install a lot fo software includes Firefox and Newsleecher. Cleaned the PC; register and run O&O defrag. Used TCP repiar from XP-smoker.com. Un-installed the intel pro 1000 GT and tested the line with FTP. The FTP speed is great, a file of 100mb gets a speed of 8MBs

After that only installed Firefox (clean) with only flash and shockwave otherwise speedtest.net do not work. Installed the last settings from Dann and this are the result:  http://www.speedtest.net/result/383451375.png  :po:

@Dann, does you have link or sometime from which I can use to dwonload from an AGFA site as you mentioned.

QUESTION

cablenuts is better than TCP optimizer?

Somebody ask about cablenuts and why I do not use  TCP optimizer, because he use TCP optimizer and do not know about cablenuts.

Somewhere in time I found out there was something like cablenuts and start using it since I opened a topic on this forum. But otherwise I do not have the knonhow how to use it.

Why do I not get the same info from retrive from registery as I saved your mentioned settings, because than the most of the fields stay empty???

If I use delete cablenut tweaks, is this set everything back as XP-Smoker.com does with TCP repair program???

This topic has been  decussed heavely at Speeguide's forum ,and I'm  a member of both.  Here goes in sg they suse the same value for tcpwindowsize globaalmax ,and default recive windows..     Now you can heonestly debate what is better on how to calcuate default recieve window.. Here we use caps /8 *1024  your default recive.

At sg they use the normal way of calculasting rwin http://www.broadbandnuts.com/index.php?page=14 ason here.  Before sp2 for xp the analyer use to show tcpwindowsize after the default reecive window size shows up.

Since you sre here we only support the   use  of Cablenut ,and  it's nothing negative aganist  the optimizer both are good.  Personally I said it over the  at sg's forum  I use cablenut.  Cablenut always gave me the best speed resaults: however, though Philip at Sg did make some revisons to the optimizer ,and with the new chnages in the optimizer it was neck and neck sorry Dannjr just in case..

Cablenut was probably the only tweaking software that had  many settisngs that people clammed were not needed pre xp sp2  After sp2 in xp guess what the others found out they were wrong ,and they should've used those settings....

In csblenut if you delete the tweak save changes reboot  you got back to default in SG's optimer  you click file restore to pervious settings and you will get to defults.

Just my .02

Today I reset the DCHP server of the DRG and switch the internet connection to another port in the DRG (from p4 to p2) and just did a new test and its amazing.

http://www.speedtest.net/result/383845353.png

So now I'm going to beginning of this topic and try if there any diffs in the settings you advised me. I saved every setting, so it will be easy to put back them into the register and take 10x speedtest to which will be the best.

It's great to see the new results.

I have a quick question one that usually gets overlooked..
Have you tested your firewall yet to make sure your not being attacked on inbound and outbound packets.
The reason for the added suggestion is that could mess with your DHCP and cause slow down
It would be nice if you could set the IP on your machine as static as well..
The reason for that is Windows even though its been told by a router a lease time of a day or so will still go look to make sure the lease time is valid every 12 minutes or so slowing the connection to sometimes to act as if it disconnected.

Anyway both these sites have been around for quiet awhile and good for testing the firewall.

Thanx for your info Dann. But no it was no firewall problem. We use a DRG of 42 networks.  Which has 4 ports.

Port 1 is for IPTV (DTV/HDTV)
Port 2 is for Internet

Port 1 and 2 are on QOS

Port 3 and 4 are not used, because the QOS is capped.

In total we have 100Mb line, 50Mb for internet and the other 50Mb (QOS) are used for IPTV and telephone.

In the past the hepdesk adviced me wrong to put internet on port 4.  So thats why I was losing my speed.

I only thing I now try to find out is which ccs settings I gets from you guys will be best to use. As soon as find that out, later this week, I will give you the results in this topic.
