    vserver and tserver combined?

    Ok, now that there is an "official" place to put support questions, I will post my question that was deleted out of the other thread.

    What would be the possibility of combining vserver and tserver into one product?
    Four Hacked HDVR2's,
    One Still slightly confused Hacker,
    4 dogs, 8 cats, and 1 wife that is happy as long as I don't screw up her TiVo ...... Oh yeah two grandchildren that are the light of my life!

    I'll have to look at whether this could be done without modifying the protocol for either one. tserver serves individual disk sectors without interpretation, while tserver serves entire streams, so there is that conceptual difference.

    3.3 Down, 1.8 Up

    Jamie,

    I installed this full set (including the patch and mfs_import which I had not installed last time). All is well, and I am now getting 3.3MB/s download, and 1.8MB/s upload to Tivo. This compares with 1.4MB/s down and about 0.5 up before moving to this mfs release (and before moving to your 2.4.27 backport drivers).

    I did end up having to run the patch process on my PC under CYGWIN, which worked fine. As you said, it does not patch on the Tivo for some reason.

    Thanks for more than doubling the speed of my Tivo transfers! And of course thanks to tridge, jbuehl, adh, and everyone else without whom this would not have been done.

    Is that 3.3/1.8 megabits or megaBytes? I am importing a whole lot of shows to my S2 D-Tivo with the new mfs_import and getting a consistent 850 kiloBytes = 6.8 megabits. I don't know if that's good or bad since this is the first time I have imported much of anything.

    That sounds too slow. I can get over 2MByte/sec on inserts. I assume you have the usb2.4.27 backport usb2 drivers, right? What ethernet adapter are you using? It can help if you tune the tivo to a channel with no reception so it isn't capturing the live buffer to disk. This might be especially important with two tuner D-Tivo's if they are capturing both tuner outputs to live buffers.

    If it's still slow, it would be useful to hear what you see with top. Does it look like mfs_import is CPU bound and eating all the time, or is something else going on?

    BTW, thanks for your code contributions and S1 testing on this release!

    That is 3,300,000 bytes per second download speed, so to be more accurate, that is really 3.15MB/sec (using 1.05 million bytes per MB based on 1024 x 1024). Yup, this stuff is fast!!!

    Hey, thanks again jbuel for supporting this effort!

    Jamie,

    I am seeing an odd result when uploading to my Tivo, even with the updated patch. If I upload to the Tivo, but stop the upload before it has reached the end of the file, the file stays in a "Recording" state on my Tivo. As if it is still being uploaded. I cannot delete the file from the Tivo either. I must reboot to get rid of the partials. Not a big deal, but worth mentioning so see if anyone else is seeing this.

    No, I haven't changed the drivers. Do you have a link to them?

    I'm using a Netgear FA120 usb2/100baseT adapter on the Tivo. The PC also has a 100bT adapter. There is negligible cpu usage on the PC and mfs_import is using between 11 and 14% on the tivo:

    Code:

    Any time. It was nothing compared to the work you did.

    I have 4 Tivos. Is that too many?

    I notice your AppManager and tcphonehome are a bit high. And mfs_import is oddly low. What do you get when running without mfs upload in progress? I get on my HDVR2 running 4.01b:

    Aside from TOP, nothing should be above 5% CPU utilization. Note that after a reboot, it takes 10-60 minutes for a system to 'settle down'. Also, at random times the Tivo will do certain housework which will reduce uploads while those activities are going on.

    Not sure why mfs_import CPU utilization is so low. On mine, it gets up to 50-60%.

    Yes, I've noticed that too. I believe they can be deleted from TivoWebPlus or from tivosh.

    I suspect this is my botch in the mfs_ftp change for insertion. mfs_ftp used to be in the middle between the socket and mfs_stdinsert for insertions, and I streamlined things to elminate this. It could be I missed something important that occurs when transfers are aborted early. I'll look into it.

    Latest are in post #4 here. IIRC, the FA120 is an ax8817x device and uses the usbnet driver, symlinked to ax8817x if you follow the installation directions there.
    Mem: 40836K used, 2864K free, 0K shrd, 784K buff, 29512K cached
    Load average: 4.66, 4.24, 3.82 (State: S=sleeping R=running, W=waiting)
    The overall load average seems strangely high at 4.66.

    Try the new drivers and tune to blank channels and see if that helps. Also, if possible, wait until the system seems otherwise quiescent before timing a transfer.

    Mfs_uberexport

    I'm trying to use this command to export to my attached USB drive. Does anyone know the correct command syntax. When I type the command with no options it does not give a list of optional commands. I am hoping that I can export to ty file with just one FSID number. Any help appreciated. I tried the following

    mfs_uberexport -o /usbdrive/test.ty XXXXXX ( FSID # )
