LargerBufferSize-40960
MaxFastTransmit-2
MediumBufferSize- 1805

PriorityBoost now at 0... interesting...

Lobo · Post by **Lobo** » Fri Oct 12, 2001 10:45 am

Well I read in one of them XP things it was 10, then Cablenut came out with Beta 8, with 0, and mine worked better at 0 so, play and find your best

SmallBufferCount is different too

Can I used this for CableModem? I am currently with Time Warners Road Runners SErvice.

If you have Cablenuts adjuster installed (Directions below in help thread) and your OS is WIN 2000, NT, XP

Actually I'm alot faster with all my settings at default. The only setting I changed was TcpWindowSize

For some odd reason, it's faster this way

Remember, my system is different. It will have different effects on different systems. Play with it

You use a very small RWIN where I use big one

Exactly

I'm on DSL PPPoE while you're on Super Fast Cable

I don't know if it is super fast Cable or not, it's not right after I format, but once I push that secret button, whoa Momma

What about Transmitworker and EnableFastRouteLookup ??

funky · Post by **funky** » Fri Oct 12, 2001 6:00 pm

Transmitworker 32, other default.

piranha · Post by **piranha** » Fri Oct 12, 2001 7:27 pm

Much more parameter to set in W2000 ans XP but where can i go to understand what each one means ??? Nothing in Cablenut help....

Lobo · Post by **Lobo** » Fri Oct 12, 2001 7:30 pm

Look on help thread below at bottom WIN 2000 Resistry

piranha · Post by **piranha** » Fri Oct 12, 2001 7:35 pm

Lobo

I read your anwer in another thread and just look there but the parameter are not all there. For example : TransmitWorker

Lobo · Post by **Lobo** » Fri Oct 12, 2001 7:36 pm

Well type it in your search engine

piranha · Post by **piranha** » Fri Oct 12, 2001 7:41 pm

already done in ms text : no results. do you mean to search in the all web ???

Lobo · Post by **Lobo** » Fri Oct 12, 2001 7:45 pm

Yes, I just changed mine to 32 as 16 is default, and I think 32 is as high as you can go, but if you find out something-let me know

piranha · Post by **piranha** » Fri Oct 12, 2001 8:02 pm

Lobo

Did I dream ......i read your setting for TransmitWorker was 64 some minutes ago.... What is good 32 or 64 ??

Lobo · Post by **Lobo** » Fri Oct 12, 2001 8:04 pm

32, your dreaming

TransmitWorker

Value Type: REG_DWORD

Default: 0x10

Valid Range: 0x10, 0x20

Description: This parameter controls how Afd.sys uses system threads. Setting it to 0x10 causes AFD to use system threads to perform IO that results from a long (more than 2 SendPacketLength worth of data) TransmitFile request. Setting it to 0x20 causes AFD to use kernel-mode APC for IO and to execute everything in the context of the same thread. This is new in Windows 2000 and can improve performance by reducing the number of context switches in long TransmitFile requests

Thanks for the info. Where do you find it (i have some others i want to understand).

Valid Range: 0x10, 0x20. Is 32 in the valid range ?

Explain a bit what is TransmitWorker, i dont really understand

Lobo · Post by **Lobo** » Sat Oct 13, 2001 9:00 am

0x10 = 16
0x20 = 32

darkreign · Post by **darkreign** » Sat Oct 13, 2001 9:31 am

well lobo said 32

so its 32...

actually if you etner 0x20 you get 32, so i would assume from the info that its 32 now as far as what it does... i honestly have no idea but ill look into it..

piranha · Post by **piranha** » Sat Oct 13, 2001 9:43 am

darkreign

I repeat.....on which site did you find the info and what do TransmitWorker.

darkreign · Post by **darkreign** » Sat Oct 13, 2001 9:46 am

"Explain a bit what is TransmitWorker, i dont really understand"

i found it on microsoft.com
do a search there on the main site
i also have a .pdf file with the same info as on the microsoft site but in .pdf form.

piranha · Post by **piranha** » Sat Oct 13, 2001 10:21 am

i hate to search in MS site, it is a real labyrinth. Find nothing or hundreds one wich dont help.......

thanks Lobo

I already read it but it is not clear. Anyway, important is good settings....but i prefere to understand.

AFD = ?

IO = ? In and Out ?

kernel-mode APC ?

SE= Search Engine, search the web

cablenut · Post by **cablenut** » Sat Oct 13, 2001 12:24 pm

AFD 'afd.sys' would be the Ancillary Function Driver. This is the Kernel mode control system for Winsock. Winsock is a widley used programming API built on top of TCP/UDP. Such things as FTP, and HTTP both use Winsock API calls.

I/O would be the Input, and Output or "read & write" of the AFD.sys driver.

A TransmitFile request (call) is used to "Upload" data not "Receive" so thus any setting that quotes something like TransmitFile would only affect your Transmission i.e. Upload.

When you set TransmitWorker to 0x20 (32 decimal) AFD will use longer TransmitFile requests (2 page lengths or more i.e. > BuffLength) more efficiently by reducing the number of context switches between multiple threads/requests.

Sorry I probably put it to complicated for you to understand.

darkreign · Post by **darkreign** » Sat Oct 13, 2001 12:58 pm

Afd.sys is the kernel-mode driver that is used to support Windows Sockets applications. the default is calculated based on the amount of memory detected in the system

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\Afd
\Parameters

oops sorry cablenut didnt see the post until after i hit submit

thanks for explaining what it is.

piranha · Post by **piranha** » Sat Oct 13, 2001 1:03 pm

Thanks Cablenut

yes it is complicated but i understand it is like rwin tweak (longer requests and reducing switches)but in another context
