Crazy upload speed stuff

[EvILEyE]

Kinda hard to explain, like most of my connection problems:

For some reason I cannot upload faster than an average of ~20KB/s a to any one send, but If I were to open multiple connections to the same person, the sum of the sends speed would be greater than what it was at 1 send. The more connections I open, the greater the sum of the upload speeds. This happens with FTP (g6/serv-u) ICQ and IRC. Various speed test show my line to be around ~1.3mbps upload (averaged)
and I can go that fast.. I just have to open about 10 different connections

I'm running a Win2k Pro Box on an AMD K7 600Mhz 256MB Ram System w/ the following tweaks applied (copy/pasted from TCP/IP analyzer):

TCP options string = 020405b40103030201010402
MTU = 1500
MSS = 1460
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240

Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON
Time to live left = 48 hops
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000

Please help thank you in advance..

Is this Cable or DSL

[EvILEyE]

stupid me.. lol
I had it in the first draft that I accidently closed..
Cable.. www.starstream.net = local provider >.<

edit:
Would be a good provider if I didn't have all these weird problems..

[Lobo]

Do you have Cablenuts adjuster, I forgot to ask you before

[EvILEyE]

cablenuts? never heard of it.. guess not

edit:
I've used Dr. TCP though.. tried various settings with that..

[Lobo]

OK, with DR TCP try changing Tcp Recieve Window to 513920, 522680, or 524176


Download to desktop DRTCP019.exe, you may change alot of settings with this, first select your adapter, after changing anything play with it until apply button lites up, then click on it. Then REBOOT for it to work.

[EvILEyE]

will try that...

[EvILEyE]

nope tried all 3.. same results..

[Lobo]

Put 513920 in, take analyzer and let me see it

[EvILEyE]

k

TCP options string = 020405b40103030301010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 48 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

[Lobo]

Thats crazy, maybe some help here


Also how to do speed test in help thread below in signature

[EvILEyE]

>.< not that page again! god help me
You're not the first to refer me to that page heh.. ohh well..

[Lobo]

Yes alittle confusing but full of info, see you in a couple of months

[EvILEyE]

I was told that my ISP could be doing something as stupid as capping my upload speed per-port? is this possible?

[Lobo]

I don't know, you don't have NIC card set on full duplex do you
and NIC should be on IRQ by itself

[funky]

Most companies do that to save bandwidth.. evil isn't it?

It might be the other end's problem. Your friend may get a slower connection and average 20K. You could possiably ask nicely to the company to lift the cap off, or you can go to the extreme and uncap. but Uncapping will get your internet services Terminated and possiably a few weeks behind the bars, and Since you are on Cable, it's pretty easy to detect if you uncapped or not. You can't uncap on your end, unless your internet service has some flaws though..

LOBO what do u mean by saying crazy.
i have the same results as evileye except hops at 49.
i have also read the link but dont understand what your getting at.
dont mean to be rude but could u please explain why.
oh my cable modem is ntl motorola surfboard 4100
my upload 512
my dl 128
dl average=25k

[Lobo]

I have no idea what you are talking about
And since you did not take time to fill out form when joining I know nothing about your system, you left no analyzer test results,
so I have nothing to work with
