ok!

One tip for testing:
the result will not be obvious if you test just one thread.
try to do 10 speed tests at same time, and add the values together.

You can download a free multi-threads download manager called NetTransport and try to use it to download a 100mb file with 10 threads. this is ...

Microsoft says that "Timestamps help TCP measure round trip time (RTT) accurately in order to adjust retransmission timeouts" ( http://www.microsoft.com/windows2000/techinfo/reskit/en-us/default.asp?url=/windows2000/techinfo/reskit/en-us/regentry/58813.asp )

However I have not see anyone here use ...

I'm using FreeBSD.

the rcvWindow is supposed to be 256960.
However i get 276854 from the analyzer.

wangnan

if your "Segments Retransmitted" is huge number(more than 1/4 of "Segments Received"), try to increase the value of TCPInitialRtt (DWORD) in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{#Interface}

Default is 3000 (Dec.), try 5000 or more.

How to make WIN2000 to support UPnP?
I know UNIX/LINUX has already support it.

What's its RWIN?
Can I set my own MTU, like 16384?

I'd like to say that the minimum of SessionKeepAlive is 60000.

If you want to add a ramdisk to increase your browsing speed, why not use Netscape 7?
NS7 can make a RAM cache itself for browsing.
I set the 32768mb RAM cache, and 32768mb HD cache.

Can anybody give me some idea how to reduce "Destination Unreachable", "Failed Connection Attempts", "Segments Retransmitted", and "No Ports"?

Add these REG_BINARY values into HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Conferencing\RRCM
:

RTCPrcvBfrSize := 00 20 00 00
NumRTCPPostedBfr := 00 02 00 00

=)

wangnan

After I spent whole day on the problem, I finally found a solution.
1. Open Regedit.exe
2. Locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Conferencing\RRCM
3. Add DisableWinsock2 = 1 (DWORD)

Done.

After I optimized with cablenut, there is no video and audio appeared in Netmeeting, but Remote Desktop and File Trans. are normal.
Can anybody give me any idea?

Or, can you now test your Netmeeting and see if yours got same symptom as mine!

THANKS A LOT!!

I mean how to configure the Networking Load Balance Service from Windows 2000 itself.

wangnan

I have installed 2 NICs.
Anybody can tell me how to use NLB?

Thanks very much!!

p.s:
WIN2K ADVANCED SERVER is better than WIN2K PRO, since we can uninstall useless components and services.

Can I change to "Standard PC"; re-assign IRQs, and then change back to "ACPI PC"?

7 Realtek RTL8139/810x Family Fast Ethernet NIC
7 SOHOware 10/100 PCI Network Adapter
7 Conexant's BtPCI ...

wangnan

yes, i'm thinking about combining two NICs together in order to increase throughput.
I think dual network chips may help on throughput or response time.
However, the only thing i could find is NLB. I wonder if there will be a kind of technology can do the combination, like Diamond's Shotgun(TM).

Take a look at:
http://www.windows2000faq.com/Articles/Index.cfm?ArticleID=23258

I've tried RandomAdapter = 1(dword), but why it does not work?

By the way, Does Windows XP Professional support Network Load Balancing Service?

Thx.

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

If we set MaxFastTransmit = 64, then what about MaxFastCopyTransmit?
