Why Does Tivo Take So Long To Boot Up?

    The Mini boots even faster, which bodes well for whatever new TiVos are coming down the pipe since the Sister chip to the one in the Mini is even faster. Although the Mini might be helped along by it's SSD storage which the new unit likely wont have.

    How much SSD storage do you think it has ?? I would think just enough for the software, 4Mb or 8Mb like a USB stick.

    More then that. I think TiVo uses about 500MB for the OS partition and it has two of them so that if a software update fails it can fall back to the old one. Although since the Mini doesn't have to maintain a DB for guide data it might be able to use less, but these days SSD is so cheap they probably have a couple GB in there just in case.

    Ugh. I can honestly say I STOPPED buying their products because of their advertisements on TiVo.

    Unless you actually *informed* the advertisers, what you did was meaningless.


    BTW, it was mentioned before briefly in this thread, but IIRC, in previous threads, people have mentioned (paraphrase) that the binaries' signatures are actually checked, or something like that. Basically, a very thorough security check.

    But yeah, Premiere 4 is a ZILLION times better than Series 3 OLED... But none is anywhere near as fast at rebooting as a S1, which is SO FAST. Though a S1 is SO SLOW when getting into Now Playing if you have an expanded drive (like 20 seconds or so..)

    That cache card helped with that. But those were simpler times. They've added a LOT of features since then, and gotten a lot more strict with security.

    That's because the Mini doesn't have a "hard drive" to boot up so to speak like the other boxes. But you're right, it's night and day with the Mini compared to any other TiVo.

    While the hard drive may play a role, I still think a big portion of the time is CPU bound. TiVo performs a lot of security checks during the boot up all of which should be sped up by a faster CPU. If it does in fact do a full scan of the HDD, like someone above suggested, then that may slow down a real TiVo a little but with a faster hardware that should be helped along a bit as well.

    For a properly working TiVo boot time should never be much of a problem, not the same as a computer. I don't think TiVo should spend any time reducing the boot time as that will not sell anymore TiVos and it not a feature needed by anybody.

    I agree. My TiVos are on a UPS, so unless they get a software upgrade or I intentionally pull the plug for some reason they never reboot.

    Great in theory, less in the real world. Tivos hang just like everything else, and sometimes need to e rebooted (as workarounds for other bugs)..

    and the power goes out. You shouldn't HAVE to have a UPS. (I used to have one, mostly for my XS32, which CAN easily corrupt the hard drive.. battery died, so it ironically wasn't UPSing at all and would beep at ~6:30 AM.)

    Outside of October 2011 (when I lost power for 7 days and made good use of my back up generator) I have a power loss less than once a year, I can handle a 5 min re-boot, if one were having a power loss every week than get a UPS, even a 1 minute re-boot would be a pain every week when your recording/watching. As for hang ups, that also use to happen a few times in a year with xfers using the wireless system, with Moca in the last 6 months I never had any hang-up on my TiVos.

    I wish my power was that reliable.

    Even if it's flawless I think a UPS is worth it. When lightning blasted the heck out of my house and burned down a fair chunk of it my TiVos survived. I can't say the same for any electronic equipment that wasn't protected.

    I also have brownouts and power surges that my UPS kick on to protect my TiVos and other electronic devices. Every weekday morning at 9AM there is a power surge that kicks on all my UPSs.

    One time one leg of the local transformer died and for close to ten minutes there was only around 75 volts on the electrical outlets before the transformer finally died. My dozen or so UPS units protected all my electronics during this. Although one or two of my lamps died during the brownout that were not on a UPS and only on a surge protector.

    Lightening strikes just mean it's time to upgrade.

    I've been told the slow TiVo boot time comes down to one simple word ...

    Linux

    FYP.

    It would be 10 times slower if windows!

    Both these statements are incorrect, IME. My main system is dual-boot. Windows 7 Pro x64, Ubuntu 13.10 Linux x64. Boots in about the same time with either OS. I've got a netbook that is XP x32 and Ubuntu 13.10 x32, and the same thing applies. Both OSes boot in about the same time.

    It ain't the fault of the OS.

    Please compare the boot time of a custom Linux kernel to a standard Windows kernel!

    Edit: The main difference is file checking on the file system; so, compare Windows file checking to Linux file checking!

    One thing that slows a TiVo's bootup is the security checks it performs on the root filesystem. It checks for unauthorized modifications to the TiVo software, and will overwrite them with approved software, if detected.
