Add this to registry MaxFastCopyTransmit,
MaxFastCopyTransmit

Value Type: REG_DWORD

Valid Range: 0–0xFFFFFFFF

Default: 128

Description: This parameter controls the maximum size of data that uses copy instead of cached memory on the fast-path. Fast I/O is essentially copying data and bypassing the I/O subsystem, instead of mapping memory and going through the I/O subsystem. This is advantageous for small amounts of data. Changing this value is not generally recommended
I changed it alittle, mine is 192 hex

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AF
D\Parameters,
This is what it should look like in registry, Hex, just put 8 small f's, =0xffffffff (4294967295). You can play with this if you like

Play with this value until it makes you the fastest, someone said try 8192 is better, 8192 Decimal

BufferMultiplier is set to 1800

If Receieve Window does not apply as someone stated then
change yours and see,

2002-08-05 09:39:34 EST: 3232 / 350
Your download speed : 3232869 bps, or 3232 kbps.
A 394.6 KB/sec transfer rate.
Your upload speed : 350979 bps, or 350 kbps.
Seems like broadband .. above the 1mbit barrier!

4.7 Results
megabits per second

Run the test again Discuss in the forum
Details

Your raw speed was 4711178.71 bits per second which is the

same as:

Communications

4.7 megabits per second
How communication devices are rated. Kilo means 1,000 and

mega means 1,000,000. Examples include 56k modem and

10Mbit Ethernet

Storage

575.1 kilobytes per second
The way data is measured on your hard drive and how file

sharing and FTP programs measure transfer speeds. Kilo is

1,024 and mega is 1,048,576.

1MB file download

1.8 seconds
The time it would take you to download a 1 megabyte file at

this speed.

Alot of the Cablenut values stated in some posts are default

values, I thought if you left it blank it used default settings, but

if you leave MaxHashTableSize-blank, not only does it not enter

default value, it does not enter MaxHashTableSize at all.

MaxFastTransmit

Value Type: REG_DWORD

Valid Range: 0–0xffffffff

Default: 64 KB

Description: This parameter controls the maximum amount of data that is transferred in a TransmitFile request on the fast path.

Changing this value is not generally recommended. Mine is 64040

Try to set MaxFastCopyTransmit = 8192
i've set it a month ago, and it works good.
just try it.

Yours is quick, have to try it late tonight, now try mine, lol

Lobo, do u mean add D_Word MaxFastCopyTransmit into

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic
es\AF

D\Parameters and give it a decimal valu of 192 ?

and the

DefaultReceiveWindow=256960
DefaultSendWindow=40960

do u base on ur caps or just put the number there ?

Lobo · Post by **Lobo** » Fri Aug 02, 2002 3:05 pm

Yes Just add it, nothing to do with CAPS

ok just to make sure b4 i reboot..

Righto, lol

Lobo · Post by **Lobo** » Fri Aug 02, 2002 4:16 pm

Mine is 64, works better

Hey Lobo,

What if I dont have a parameters folder under AFD?

I got Enum and Security

Lobo · Post by **Lobo** » Fri Aug 02, 2002 7:03 pm

Well, there's 2 things you could do, see #17 in help thread and edit registry or download Cablenut which would add it, Parameters that is:

here version 4.08, if you have SG's patch installed leave it for ping tests

Well it changed the numbers when I tested the tweak but im not really seeing a change much more than loading my web pages a bit faster.

hey lobo, in between all this tweaking and helping here at the forum, Do you have any time left to actual download stuff with your super tweaked connection??? lol

Lobo · Post by **Lobo** » Sat Aug 03, 2002 7:41 pm

Alittle, but I don't download a bunch of mess, watch a lot of sports though, in fact, their is a NASCAR race about to come on, later
