Help! Please! Tytool/Windows XP Network Performance is Terrible

[lophophore]

Help!
I just got a new computer with Windows XP and I am having terrible extract speeds with TyTool. I don't think TyTool is the problem at all, but I am hoping somebody can help me.

New Box: Asus P4PE 2.4 Ghz P4. Integrated Broadcomm 10/100 adapter. Get's good file transfer performance with Win2K box and Linux boxes, as well as downloads over DSL. Piss-poor transfer speed with the TiVo, UNLESS I force the network adapter into 10 MB mode.

Getting 1 MB every 1.2 sec at 10 MB, getting 1 MB about every 25 sec at 100 MB. The TiVo has a TurboNet in it.

I still have the Win2K box. It is a Asus A7V333 with a Athlon XP 2000 (1666 MHz) and LinkSys 10/100 card. It gets good performance from the TiVo at 100 MB.

I tried to sniff the line using Ethereal on one of my Linux boxes, but my network is glued together with a Linksys 10/100 switch, so I can't see the traffic from the XP box to the TiVo. I am going to try to borrow a 100 MB hub to see if I can then get a good capture.

I realize this is not the typical kind of problem that gets posted here, but I am getting desperate and hoping that somebody has an idea how to fix or at least troubleshoot this problem.

Help!

Others have reported similar issues. I run XP and have no problems getting ~1.5MBs. The 10/100 hub will let you sniff the traffic, and what you'll see are small packets coming from the Tivo. I've brought this up to Josh before. This has a BIG negative impact when using a hub, as utilization goes very high (see my other post here (http://www.dealdatabase.com/forum/showthread.php?s=&threadid=20726)).


Not sure what the root cause is for what you and others see. Only thing that I can come up with is a switch that doesn't properly negotiate full duplex, or cheap switches don't have the horsepower to handle the small-packet traffic.

I've had the same problems -- I had the Tivo and PC on a cheap switch from a company called "Add-on" and things were very slow (30+ secs per megabyte) - swapped that for my Linksys Wireless router / switch (using the wired part of the network, not the wireless) and things are flying now (2.9 megabyte / sec).

Not exactly sure of the problem here, but that switch is going in the bin!

I just got a new system up and running a week ago that has a Realtek RTL8139 fast ethernet nic built into the motherboard and my transfer rates from my TiVo using tserver went from 0.67mb/s on my old system to just over 2.0mb/sec. I would guess the Realtek chip has something to do with it.

Turn off the QOS on the interface (if it is on). Also disable the Deterministic Network Driver (if you are using VPN software). I was getting horrible performance (.56per sec), now I am getting around 1.98 per sec.
