What startup times are you seeing as normal?
I am running MAC Mine i7 quad.
I am seeing around 8 seconds after full close of Channel App. Very fast after it is running.
Synology DS716+ wired.
8-10 seconds. QNAP HS-251+ over wireless 802.11ac.

It’s just the initial loading. Like the app is not yet loaded to the ATV. It will take about 19 seconds for me.
Qnap ts-453A
Once its loaded and you go out to the ATV homepage and then go back to channels, that one was quick like a second.
maybe i should have mentioned that when i load clean it is still 2-3 seconds but im only loading 31 channels because im OTA. and everytime i hit the guide limit, its again 2-3 seconds to get the next period. so maybe thats whats changing my results and not the fact its an i5 6gen with SSD.
I have about 300+ channels. Time to prune it down and remove the sd channels.
I removed some and down to about 270. Now clean start up is down to about 13 seconds.
So i guess it depends on the number of channels you have for the loading time.
Now loading guide after each 4-hour block takes about more than 15 seconds. Not all channel guides are loaded 
Down to 145 channels. Loading takes about 10 seconds.
Lots of channels with incomplete guide. Some hours they are missing guide info and you can’t tune in to the channel in the guide grid if they don’t have any guide information. Will have to use the thumbnails when you swipe down to tune tot he channel.
Would removing channels help? The old Pre-DVR Channels launched fine with the same number of channels.
27 seconds to open the 2.1.7 with a 2009 Mac mini.
7 secs for me. Before DVR, it was a few seconds. I cut my 383 channels down to ~150 and didn’t seem much of a difference.
Core i3 3.1GHz with Ubuntu running off a USB flash drive. all wired ethernet.
A new Testflight Beta was just put out. For those on the beta, please give it a try and see if launch times have decreased. Here are my personal numbers:
BEFORE
Time to start: 7.395725s
AFTER
Time to start: 1.886984s
Before: 27s
After: 10s
For give me but how does one install this new version?
@maddox your times are so accurate. Not sure how you are testing. I am just counting 1000 1, 1000 2 etc 
Mine is about 8 seconds for 2.1.7 and about 3.5 seconds for the New Beta.
But a strange thing happened when I first started testing. Both were coming up about the same 3.5 seconds at first when I installed the New Beta and test it first. Then after a few test I noticed the DVR Tabs were missing. Then I tried multiple times again until the DVR Tabs started showing again and that is when I saw the 8 seconds on the 2.1.7 version and the 3.5 on the Beta. So twice as fast with the DVR Tabs.
Also, I have noticed this before. For the 2.1.7 version I see the “loading” screen when I swipe up instead of the normal current screen. This did not start with 2.1.7 but has been there I think since at least the App Store version got the DVR support. The New Beta does mot do this. When you swipe up you see the current screen. Seem like the loading is not complete on the 2.1.7 version. Confusing.
Very significant improvement.
Before 19 seconds
After 6 seconds
Still double the time before DVR. What kind of changes did you guys make if you don’t mind me asking?
Before: 10.53s
After: 4.14s
We have to translate the guide data from Channels DVR to what Channels expects, so that everything is normalized at the app level: DVR guide data, SiliconDust guide data, etc.
DVR data is a bit more involved. I just made the translations a bit more efficient.
The app tracks the time to launch and prints it to the log. That’s how I’m getting the precision showing.
