    Is the ethernet port on the Mini only 10/100? I'm pretty sure my switch is indicating a 10/100 connection to my Mini.

    This is all well and good, but what does it really matter? If you can use multiple minis with HD quality from a base unit without problems, who cares? Is there a potential problem someplace?

    The OP is using kmttg though, so the faster the transfer the better.

    Sure, its nice that between TiVo devices its fast enough, but when getting the files to the desktop you want that as fast as possible, especially if theres a big queue to go through.

    Ok, so use case 1 is when there are lots of files to transfer to a PC. I get that it will transfer faster, but that seems, in most cases, a small benefit overall unless someone is really looking to watch shows concurrently on a local network or PC. However, if having this increased speed allowed transferring more quickly to an iPad, I could see the benefit.

    Exactly. Again, this is all a first-world problem right. :D I'm not really complaining as much as I'm curious to understand why the Tivo gigabit transfers seem slower than I would expect. Tivo says it's a 10/100/1000 port on the device, so naturally I kind of expected performance closer to a local PC or PC transfer (minus any work Tivo needs to do).

    Take for example a 7.45 GB show I just downloaded.

    Using kmttg it took 8:27 at (117.6 Mbps) hooked up via a gigabit connection.

    I then transferred the same file from my PC to my Mac using the same gigabit connection and it took 2:24 at (434 Mbps).

    It's more my curiosity as to why the performance of gigabit on Tivo is not that much more than 100 Mbps connection.

    True on the iPad streaming, although I think with an iPad you'd be maxed out at 300 Mbps on an N connection....and even with that you'd have to have a perfect setup and the network overhead will still knock 40% off the rate.

    Transferring that same 7.45 file from my Mac Pro to my MacBook Air connected via N with a transmit rate of 300, I still max out at about 185 Mbps.

    So yes, the gigabit on the Tivo would help.....and as you can see, it's still below what I would expect.

    Idiot here, so patience is appreciated, lol. Using Tivo Desktop with new Roamio base. I used to transfer shows from Premiere to laptop over wireless. This was done very slowly. Basically, the shows transferred in realtime or slower. I'm all wired now on a gigabit network using a gigabit usb 2.0 adapter on the laptop. This doesn't give me gigabit bit speeds on laptop, but has bumped it up. Tried transfer from Premiere to laptop and then from Roamio to laptop to compare performance. Premiere transferred shows in half the running time of shows while Roamio transferred shows in a third of the run time. I'm curious if anybody is running an all wired gigabit network that includes a PC with a gigabit connection and a Roamio Pro or Plus. If so, what are the transfer times? Thanks folks.

    That's what I just ran. I have the Roamio Plus hooked up directly to Airport Extreme on a gigabit connection. PC hooked up on same connection.

    I transferred a 60 minute program with a file size of 7.45 GB in 8:27.

    EDIT: BTW, same program instead transferred via a 10/100 switch, completed in 11:56 at (83 Mbps).

    This was using kmttg. Not sure if Tivo Desktop would be slower or not.

    My curiosity is piqued now.
    I think when I get home Ill do some GigE transfers as well.

    Ill have to fire up a shelved Windows laptop since I only use a MacBook Air, but I am just too curious how fast it will go on GigE connection!

    On mine I still see a slight difference with PS being 1-2Mbps slower then TS. I'm connecting via MoCa so I'm constrained by the 10/100 port on the MoCa adapter.

    I've only done a few tests but from what I've seen using Tivo Desktop, pulling from the Pro/Plus, they do about 140-200Mbps to the PC. I haven't seen anything under 140Mbps. I've not pulled from the PC yet to check transfer speeds nor done any Pro<->Plus transfers yet.

    Can I ask:

    1) What version of Tivo Desktop are you running?
    2) How are you measuring speeds?

    I haven't yet done a test on Tivo Desktop yet so I might try later.

    With my Roamio Pro I get 190Mb/s transfer rates, at least the last time I looked, from my Roamio Pro to my TiVo Desktop PC or KMTTG. As reported in the transfer history in the DVR Diagnostics section.

    Where? Only thing I see in the DVR Diagnostics is Tuner and Cable card info.

    Sorry about that. It's "view Network Diagnostics" on the network page. And then the transfer rates are under "view Transfer History"

    I got around 100-110Mb on my tests
    I transferred a 17.3GB file in 24 minutes.

    I was using kmttg and a roamio plus

    So, sad to see its only 100ishMb, but if it was a 100Mb LAN then I probably would have seen 40Mbps.

    Still though, Id be much happier somewhere around 200Mb instead.

    Thanks. I'm on Windows 7 on this machine and I see in Resource Monitor a couple of numbers.

    As I transfer a show (Tivo Desktop 2.8.3) the overall Network I/O fluctuates between 160 Mbps - 196 Mbps.

    The curl.exe process itself though is measured in B/sec. That number basically tops out around 24,000,000 B/sec (around 184 Mbps).

    Doing the same transfer with kmttg, the overall Network I/O is 120 - 141 Mbps.

    It usually averages and settles around 128 Mbps in kmttg.

    So looks like Tivo Desktop might be a little quicker.

    Thanks! Found it....never knew that screen was there.

    For my kmttg transfers it looks like that reports in the 125 Mbps range.
    For the Tivo Desktop transfers, it was reporting 176 Mbps.
