READ: Rwin definition

[HalfLifer]

Heres a formal RWIN definition for everyone. Hope this helps and everyone realizes you dont need a fast processor or a gig of RAM to use an RWIN.

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. Matching the receive window to even increments of the MSS increases the percentage of full-sized TCP segments utilized during bulk data transmission. MSS is the MaxMTU - 40 bytes for TCP and IP headers.
The RWIN default is 8192 bytes rounded up to the nearest MSS increment for the connection. If that isn't at least 4 times the MSS, then it's adjusted to 4 * MSS, with a maximum size of 64K. With the Windows 95 default MaxMTU of 1500, the default RWIN is rounded up to 8760 (1460 * 6). You can greatly improve performance by setting this to a lower value such as 4 times your MSS (MTU-40). The idea is to bring it to a value below 8192. Many people have better success with 6, 8 or even 10* MSS. In some cases, however, manually setting RWIN may decrease performance because it takes the control away from windows, and if the MTU is negotiated to a different value, then the size of the RWIN is no longer an whole integer multiple. For this to be effective you must make sure your MTU is set where it will not be negotiated to a lower value.

"Ultimate NIC buffer tweak for speeding up your connection: www.cyberwizardpit.com"
I looked and couldn't find it. All NIC Buffer tweaks I've tried so far have done nothing but slow me down... I'd like to try this "Ultimate" one.. maybe it will speed me up.

[EvilAjax]

LOL.. yeah but what exactly is the file? I don't see NIC Buffer Tweak... and what exact changes does this file do?

[EvilAjax]

Oh and if RAM nor CPU matter then why do the Cyberwizard Pit tweaks have these requirements?
▪ Requirements : 500MHz or faster processors with 128MB or more RAM.
▪ Requirements : 1000MHz or faster processors with 256MB or more RAM (512MB recommended).
I'm confused?

Evil, email me and I'll give you all the files from cyberwizardepot

[EvilAjax]

Thanks, but I don't want any files unless I know what exact changes it does.

[Lobo]

Get your checkbook out, and RAM and CPU size do make a difference unless you use itty bitty RWIN

[HalfLifer]

Only RAM matters for a nic buffer tweak.

EvilAJax,

They are a nic buffer tweak.

I ran the cyber 2000 Deluxe tweak on one of my computers. I notice that it changes a lot of settings in the cablenut adjuster... to include RWIN.

Is the cyber 2000 Deluxe tweak a NIC tweak? Why does it change my RWIN?

[MadDoctor]

If it will help clarify things... I’ll fire up my other Win2K machine that is fully configured with cablenut and SG patches. I’ll take a screen shot of the cablenut adjuster settings. I'll then load the Cyber 2000 Deluxe tweak. I’ll then take another screen shot and post it. We can then compar the two screen shots and talk about what... and why... settings in the cablenut adjuster have been changed by Cyber 200 Deluxe tweak.

[HalfLifer]

MadDoctor,

Dont, please. Deluxe is a fee based program...showing settings over the internet would cause some problems .

[MadDoctor]

Okay.

[HalfLifer]

Thanks for understanding....


I was part of their team, and I know Rick poured his heart and soul into these...and Lobo just pours the settings out like they are his. *sigh*.

Please don't lie and make a fool of yourself. It doesn't help spelling Cyberwizardepot either. Obviously, you have no clue where the tweaks are online and you are most likely not to find them.

[HalfLifer]

He posts the deluxe files and he'll have a large lawsuit lmao

[HalfLifer]

You seem to be friends with him and know his stuff..you contact him.

[MadDoctor]

A few questions.

1. If Cyber tweaks are tweaks for the NIC… how come it makes so many changes to other settings that are shown in cablenut? Cablenut does not have a NIC tweak (I'm on a quest to learn)

2. If I load both of the tweaks below on to clean systems, will I get a different RWIN for each of the Cyber tweaks? I could do each of the two tweaks… and then report any change with respect to the RWIN without actually revealing the RWIN. That would put an end to this RWIN war.

Cyber2000Deluxe
Requirements : 500MHz or faster processors with 128MB or more RAM.

Infinity2000Deluxe New!
Requirements : 1000MHz or faster processors with 256MB or more RAM (512MB recommended).

I've got time and money. What the heck. Tweak until it's time to format.

And I haven't seen you post there for weeks..
