Kastoo
Some lists contain tens of thousands of channels, movies and episodes. Loading them and moving around them takes memory and bandwidth, and on modest devices you notice it. The good news is that it can almost always be improved without changing your list.
1. Understand the first load
The first time you open a list, the player has to download all of it and sort it. With large lists this can take anything from a few seconds to a couple of minutes. Kastoo then keeps a copy, so from then on it opens much faster and refreshes the list in the background.
2. Xtream Codes is better than a huge M3U
If your provider gives you a server, username and password, add the list as Xtream Codes. That way the player requests the categories separately and each series’ episodes only when you open it, instead of downloading thousands of episodes in one go. We compare them in M3U or Xtream Codes.
get.php?username=…&password=…, Kastoo detects the details and uses this fast mode by itself.3. Hide what you do not watch
If your list includes categories from other countries or topics you are not interested in, hide them: you will have less to scroll through and will find what you want sooner. In Kastoo, Settings → Organise channels lets you hide and reorder channels and categories.
4. Refresh the list less often
In Settings → Refresh the list you choose how often it is downloaded again: every 6 or 12 hours, every day, every week or only manually. With very large lists and a limited connection, once a day is a good balance.
5. Look after the device
- Restart it now and then by unplugging it for a minute.
- Close the apps you are not using: on TV boxes with 2 GB of memory, every open app takes its toll.
- Free up space: if storage is almost full, everything slows down.
6. If it falls short, change the device
With large lists, the difference between a basic TV box and a modern one with 4 GB of memory is very noticeable when opening the app and browsing movies. You will find our recommendations in the best TV boxes for IPTV.
| Problem | Quick fix |
|---|---|
| Slow to open the first time | Normal: afterwards it opens from the saved copy |
| Series take a long time to load | Use Xtream Codes |
| Too many categories | Settings → Organise channels |
| Stutters when moving around | Restart and close other apps |
| Always slow | A device with more memory |
Frequently asked questions
How many channels make “a large list”?
From around 10,000 items (counting channels, movies and episodes together) it starts to show on modest devices. Some lists go beyond 100,000.
Does internet speed matter?
For downloading the list, yes. Once it is loaded, moving around it depends mainly on the device’s memory.
Does clearing the app’s data help?
Only as a last resort: you would also delete the saved copy of the list, which is what makes it open quickly.
