Loading an M3U file Emby "Live TV" is taking a very long time

[GaryG 5]

I just purchased an Emby Premier Subscription, I have an IPTV provider,  I'm Trying to load an M3U file which is about 80 MB, and is on my local network.
It is taking a very long time to load. So far I have only gone to about 11%, I  dont want to just let it load for 24 or more hours, which is what I estimate it might take to complete.

Any thoughts on why its so slow? There are alot of channels.
Any commentary would be appreciated.

There was'nt a problem per sey,  "Refresh Guide Data" was very slow in refreshing. Ive loaded the M3U file into Smarters IPTV, and other apps, it took seconds to load.
I can tell you that it is alot of information. thousands of entries. What exactly do you want me to look for in the log?

Thanks

It gets to about 10.1 % quickly then slows down to a point where it gains 0.1% every few minutes.

I can hear the hard drives in the Synology clicking away while this is going on. Unit is healthy and fine.

Hi there, please attach the complete emby server log file. Thanks.

[GaryG 5]

Attached. Thanks.

FYI: Ive edited the M3U File, trimmed it down from 80M to about 65M.
Took out alot of lines of data that were unneeded. Still the same. Guide Refresh starts at 10.1%, and crawls.

[GaryG 5]

Ive been searching for a soution...no luck so far. The "Large M3U" problem is an old one as far as I can tell, and not isolated to one application.

I can try to trim down this M3U file more, But I dont think that will help. Its weird that it starts refreshing, goes to 10.1% rather quickly, and then just crawls so slowly.
Ill keep looking.

Let me know if you have any ideas or suggestions.
Thaks

HI, have you seen the option on the m3u setup screen to only import channels from certain groups. Does that help?

[GaryG 5]

Yes I have, I havent tried it because my IPTV Provider isnt listed. I can try it. Which Provider do you suggest?

Thanks

What do you mean provider isn’t listed?

When you type in your zip code, a list of providers is populated. Im currently using a provider not listed. Ive tried a few different providers, same result hangs at 10.1 %

[GaryG 5]

It refreshes at a rate of 0.1 % every 1 Minute and 33 seconds.

That’s guide data. M3u is a tuner source

OK Im breaking up into Groups...I think I understand where youre going with this.

[GaryG 5]

Breaking the file up into groups, is working. One final question,  I can hear the hard drives clicking away when we are streaming, is this something to be concerned about?  Id hate to burn out a drive, they are brand new.
