I gree with adminstarter about higher RWIN's, it depends on your systen specs how large you can go, I use 64240 witch is a good recieve window so DSL and Cable users can use it in help thread, but it seems everyone is in to online tests instead of real tests, so

And Tweety Bird, I know you are chomping at the bit, if I had your speeds I would be too, but please, none of your childish remarks because it is not YOUR way

I tawt I saw a puddy tat I did, I did...... his name was Bobo.

Oh wait a minute let's see...... first it was 256960, then defaults, then 64240 and now 584000.... what's next? Make your mind up and stop posting this crap because nobody cares........ and you speed hasn't changed with any of them.

Keep adding, maybe someone will beleive you, why did Cablenut have in his old program a RWIN of 524176

Why did the CableNut Team review and approve the new CableNut add-on with a RWIN of 64240 for caps of 1500 + with the exception of OOL that we suggest 128480?

I'm a guy tweety, 64240 so DSL users and Cable can both use it and system specs don't apply, if I were a girl, I wound be in the movies (pron)

, I not arguing, I just do it different, Trent

System specs never apply

, only caps and latency apply.

OK
LOBO why you use 400*1460=584000 rwin ?

Lobo · Post by **Lobo** » Fri Dec 20, 2002 1:24 pm

It's faster for me

Tweety, you have recieved E-mails from me, Signature. C.A. SMITH (Al)

Know many girls with middle name of Al with hair on their legs:

I agree with this and not with system specs don't apply, they don't if you use small RWIN:

ALL recommended RWIN values are under 1MB, so there is no way they would affect the PC performance.

Any usable CPU / RAM combination should be able to handle high-speed traffic, however slower computers overloaded with a lot of running applications tend to have slower transfers by default... Simply because there are not enough resources left to fully exploit the potential of the Netwrk card, Winsock and so on.

Still, higher RWIN is better in all cases. The only exception is that when you go above 65535, the header gets a bit bigger, so there might be a slight performance drop just above a RWIN of 65535

If there is high packet loss or latency on the line, higher RWIN is still better, simply because you have the potential of higher throughput...

Just my 2c. Quote from Phillip

I use smaller RWIN's in help thread because more people can use them, but I don't

mnosteele52 · Post by **mnosteele52** » Fri Dec 20, 2002 1:38 pm

OK I can quote others also:

Originally posted by Kip Patterson

If the RWIN is at least as large as the modem cap times the round trip time (latency), no increase in the RWIN will produce a faster speed. Period.

If the RWIN is larger than the modem cap times the latency, then data will accumulate at the router that is the choke point in the system, in this case the Cable Modem Termination System. If the CMTS is configured to retain the data, then there will be no packet loss. If the ISP elects to configure the CMTS to discard the data, then there will be continued packet loss. Moreover, if there is more than one TCP/IP connection as a result of more than one program being open or the use of a router, the latency will increase because the other data has to wait for the queue to be emptied. If you use an RWIN of 500k on a domestic cable connection, subsequent connections by the user or by other machines sharing the router will have latencies of 2 seconds!

OK so for you Courtney...... modem cap is 437.5 KB/s times 500ms (which would be your abslute maximum latency), so....

437.5 X 500 = 218750 then round that to the nearest even multiple of your MSS and you get 219000. So that should be your absolute MAXIMUM RWIN, any higher than that is a moot point.

On any high speed broadband connection your average latency is most likely around 100-200ms which can rise higher during large data transfers.

What are you talking about?

And would you get your terminology right..... all tests are done online right? So why do you call one an online test and the other a real test? Is one fake?

It's called http & ftp test. They are both online and they are both real.

What I and the others see as outsiders to this situation are two guys who simply want to help people.

I can tell you this much....this forum is one of the only forums that isn't heavily moderated because the admins think you guys can handle it in here.

Everything changes....tweaks change and methods change....but the goal is to help.

UOD.... Thank YOU

, you are EXACTLY right.... my only gripe is if you are going to help people have your facts straight, be consistant with what you post and understand what you post.

Lobo · Post by **Lobo** » Fri Dec 20, 2002 4:12 pm

Let me say this real slow so you can understand, when you install XP Pro, Microshaft auto adjusts your Recieve Window by that specs of your puter

You are REALLY showing your ignorance now.

From the Windows 2000 White Papers

The TCP receive window size is the amount of receive data (in bytes) that can be buffered at one time on a connection. The sending host can send only that amount of data before waiting for an acknowledgment and window update from the receiving host. The Windows 2000 TCP/IP stack was designed to tune itself in most environments and uses larger default window sizes than earlier versions. Instead of using a hard-coded default receive window size, TCP adjusts to even increments of the maximum segment size (MSS) negotiated during connection setup. Matching the receive window to even increments of the MSS increases the percentage of full-sized TCP segments used during bulk data transmission.

Since you don't understand it I will explain it, your TCP receive window size tunes itself to the type and speed of connection it senses..... NOT your pc specs.

You have REALLY proven yourself with this one.

You just have to understand that if you don't hard code any values 2K & XP with self adjust continuosly depending on the type and speed of connection it senses. If there is allot of congestion on your line or maybe your node is busy (all your neighbors online) it will set itself lower, if things are working smoothly it will adjust to a higher value. I don't know exactly all the values it actually uses, but they will all be even multiples of MSS, but I have seen 8760 for 56K, 17520 & 64240 for broadband connections, and those are auto adjusted to be multiples of MSS if it's a PPPoE line. I'm not sure if it only uses MSS X 6, 12 & 44 only or what, but I have never seen it use 32120 by default - or any other value for that matter. That is why I believe it is best to set your own values rather than let it self tune. Dannjr or Philip might know if it defaults to any other values.
