Proxomitron reduces RWIN to 32768

JJoe,
I tried Privoxy. When the page loaded at all, the test for RWIN showed 32768, as for Proxomitron. Pages seem to load much more slowly with Privoxy. I think I'll stick to Proxomitron.

Very interesting (easily amused aren't I ;-).
So any Proxy causes 32768...
Hmm. Look through all the TCP Optimizer's settings for any 32768s.
http://www.speedguide.net/tcpoptimizer.php
I see under Advanced Settings "LAN Request Buffer Size". What is it set at? If 32768 does changing it change the RWIN?
Did you install any software from your ISP?
Is there something you have or do that most other XP users do not?

LAN Request Buffer Size is 16384.
I did not install any software from my ISP.
How would I know the answer to the last question? Such as what?

I agree that it is quite a question but there must be something different...
Thing is I don't have XP to test with.

Which firewall are you using, if any?
Reads like most of people here don't use XP's.

If you are using the Windows'firewall,

I see the possibility of finding the tcpwin size in the log, Pfirewall.log.
http://ecross.mvps.org/howto/pfirewall.htm
http://www.microsoft.com/technet/communi...g0204.mspx
Otherwise, you could use WinDump or Ethereal to see if RWIN leaves ok.

Which ISP do you use?

Wish I had an answer for you. :-(

JJoe,
I am using Kerio Personal Firewall v. 2.1.5.
My ISP is Telus.
I am wondering if SpeedGuide is correct. I ran a speed test (through Proxomitron) on DSLReports. It showed my RWIN as 256,960 and the MTU Discovery as being on. Java was used during this test. I don't know if that makes any difference or not.
Thanks for your efforts, anyway.

Are you DSL via DHCP?
Telus' docs seem to indicate that the equipment they supply has a firewall?
What happens if you turn Kerio off?

I believe the SpeedGuide number is correct. z12 checked it with Ethereal. The Java at DSLReports seems to find the number locally. SpeedGuide looks at the data stream they received. DSLReports popularity may be why we didn't discover the problem earlier.

Wonder what value of RWIN is leaving your computer. What does the Windows firewall say?

Regarding MTU, most likely the router. Did Telus supply it?

32768 is a familiar number. ;-)
We should try to figure this out, tho.

JJoe,
The modem Telus provided is ADSL. The router is a GNet router that I bought. Telus does some firewalling themselves as part of their service.
I tried the test with Kerio firewall not running and got the same results.
I am not using the Windows firewall. I use Kerio instead.

I know but it is there.
I thought we could use the Windows firewall to help find where the RWIN was being set.
If the firewall's log showed 32768, we would look at your computer.
Otherwise, we'd look elsewhere and wonder about the SpeedGuide test.

Regardless, I don't have any great ideas for a fix.
Should I discover anything, I'll let you know. :-)

The Windows firewall is not logging anything, since I am not using it. I am not worried. The speed of page and file loading is good enough. I was just wondering how the speed guide recorded that setting after I changed things around.

Evidently rapidshare.de changed the 45 day policy and deleted the file.

For now, N45RWIN.zip has been uploaded to

Shoulda known...... Cheers

OK, you just knew that you're gonna get flamed, right? Cool What else is Proxo for, but to re-write the incoming page to eliminate whatever offends your eye. And for that matter, your very question has been asked and answered before, right here on these very pages (but I'm not gonna go track any of 'em down just now).

A glance behind the scenes shows that Guest gets a bit of special treatment, post-wise, so we can pick 'em out easily. Try this for a Match string:

<td class="post_author">*<!-- start: postbit_author_guest -->*<!-- end: postbit_author_guest -->*</td>

If you don't take out the <td... </td> tags, there's an empty box taking up vertical space. With them, there shouldn't be anything visible at all. (But of course, YMMV.)

Most of the time, Guest isn't too verbose, so the Limit might not need to be set over 1024, or perhaps 2048. But you know some times he(she) can get long-winded, eh? Drool

That should make the whole entry go away. Of course, that might make a page a bit hard to follow, what with parts of the conversation blasted into the ozone. But then again, you're an Engineer, I'm sure you just love puzzles! WhistlingSinister

RE: Proxomitron reduces RWIN to 32768
that doesn't prevent me from seeing Sir Spam-a-Lot posts from GUEST giving me a GREEN "unread posts" triangle on the front page...

yes, i use Proxo to block CRAP!
but WHY do "we" allow CRAP to be posted in the FIRST PLACE...



and no, this is not directed towards the several LEGIT "Guest" posts we get...

i'm just saying that ONE Sir Spam-a-Lot post INFURIATES me big time...

we do not "need" to be allowing Sir Spam-a-Lot a means to Spam a lot !!!



here, how 'bout this, give ALL of our LEGIT "Guests" a UNIVERSAL LOG IN !!!

and we'll even show our LEGIT "Guests" how to set up Proxo to perform that UNIVERSAL log-in FOR THEM...

'cause FACE IT, the IP Addresses of the LEGIT *and* the non-legit ARE BEING LOGGED by the forum server...

giving our LEGIT "Guests" a UNIVERSAL log-in solves the "robot posts" who are NOT using Proxo in the first place...


there has GOT TO BE a way to prevent ROBOT guests from posting...
PERIOD!!!

RE: Proxomitron reduces RWIN to 32768
I would never have seen this thread if a guest hadn't posted today.

I had no idea this was supposedly a Proxo problem. I say supposedly because I just did the patch and it didn't fix anything. I still have Speedguide claiming my RWIN in XP Pro SP2 is 32,768. It also claims that my Vista Ultimate has a SET RWIN of 32,768. That is BS as Vista has dynamic RWIN.

I have a virtual machine running XP Pro SP1 and it shows 70,800 at Speedguide and complains that I have not optimized. I dislike/don't trust that site. I prefer dslreports site to determine optimal RWIN. My RWIN in XP Pro SP1 is deliberately set at 70,800 because after much testing that was the best RWIN.

I'm not surprised that the Proxo patch didn't fix the SUPPOSED problem in XP Pro SP2 and I also have the supposed problem in Vista Ultimate. But this isn't a Proxo problem I don't think because I have the problem whether I exit Proxo and set IE to access the internet directly or whether I use Proxo. I have not rebooted since I did the Proxo fix but I don't think that should be necessary. I have two virtual machines running so it is a bit of a hassle to shut them down so I can reboot the host but I will do that on the outside chance that is needed. Since the patch just changes the RWIN in Proxo, I don't see why rebooting would be needed for the patch to work.

edit: The patch did fix it on XP Pro SP2. (I haven't tried it on Vista yet). I had to restart IE about 5 times before it showed the correct RWIN at Speedguide. But I'm not sure what was fixed because I had the low RWIN shown at Speedguide even when Proxo was exited and I connected direct to the internet.
