Why Does Tivo Take So Long To Boot Up?

    I have compared boot times with custom Linux kernels (which I helped program, specifically drivers) with versions of _embedded_ Windows. When we add needed support features to Linux to match what comes with Windows... yeah, not all that different. Sure, if we compile our Linux kernel disabling a bunch of features we can boot in 1/10 the time of a standard embedded Windows system. But we need those features to make a product. We're not out to evangelisize about an OS. Our product makes us more money if we don't have to pay a license fee to MS. I am guessing the same for Tivo - they don't want to pay $$$/unit to MS when Linux works just as well.

    Yeah, as an embedded developer, Android has been likewise a godsend - before that doing a GUI in Linux was generally painful - either you do your own UI system (like TiVo), or try to use X and various libraries.

    Embedded Windows makes doing a GUI easy as it comes with it and the development is like normal Windows GUIs.

    But then Android came around and changed the rules - doing a GUI in Linux means just putting Android on it. Making it easier is that most SoCs have Android support out of the box (less Linux support other than drivers and command line). Plus doing the GUI now just involves hiring a cheap Android developer - they're much easier to find than Linux GUI developers.

    It's also one reason why Android is ported to other platforms - MIPS is common in various markets and it too has Android for the same reason - easy and cheap UI development.

    Not to mention that the tuning adapter would cause problems constantly, I had 2 of them from Cox. Now going on my third year with Fios, No TA, and no copy 1 flag on any channel like Cox. Not to mention significantly better internet.

    The new XBox one takes about 1:20 to do a cold boot. That's why they added a standby mode that draws 19w but can boot up in about 20 seconds. It's basically running Windows 8.

    My Roamio boots up in about 2 minutes, which is significantly faster then any TiVo I've owned in the past which took a minimum of about 5 minutes.

    Does that mean 2 minutes *to the time it actually is recording*? Like I've said before, my Premiere 4 is way faster than my S3s (OLED & Tivo HD), but those are nowhere near as fast as the S1 in booting.. I know, it didn't have the security verification stuff going on..

    and the Premiere 4 starts recording (at least showing the record light on, which I trust is recording) before I can actually use it -- it's showing the "wait" gear for quite a while doing network stuff..

    I have the Directv DVR and I've never timed it but could swear it takes closer to 10 minutes to reboot. I finally replaced the battery in my UPS a couple weeks ago so hopefully I won't have that issue for a while.

    Yes. On the Roamio units the HDUI boots up almost instantly. Not like the Premiere units that give you the spinning circle for a minute or so before the UI shows up and it can actually start doing stuff.

    I had COX service out to work out a couple of problems. One was installation of a new Roamio. Yes, it is quicker than either the HD's I have or the one Premiere. He said the Roamio was quicker than the standard Cox box.

    I'd dispute that "almost instantly". It is faster, but still a few minutes. My linux box with the SSD system disk and fedora 19 takes about 15 or 20 seconds from power up to login prompt, and that seems slow too :).

    OK, yeah, my Premiere 4 crashed last night while I was recording The Simpsons, Once Upon a Time, and The Amazing Race. ONE of them was luckily *mostly* over a commercial break, but I still lost some content.

    So this is still one issue about 'consolidating to one unit', but I still think I'll do it. (Consolidate P4 & TivoHD to one Roamio 6 tuner.. Though I MIGHT keep the TivoHD, at least temporarily.)

    I meant once the Roamio boots up the HDUI appears almost instantly. The boot up takes a couple minutes. On the Premiere units the boot up takes like 4-5 minutes and then you get to sit there and look at a spinning circle for another minute while the HDUI boots up. That last part is the part I was referring to being almost instant on the Roamio.
