Improve Performance of MC

<< < (3/7) > >>

My previous server was a quad 2 core, similar to your i5-3470, which have 4 cores + 4 threads. When I made the jump to an 8 thread processor, there was a noticeable difference in MC performance.

Hi @tzr916,

I agree with you, performance would certainly improve with a better processor, but to be honest, the performance of the whole setup honestly seems pretty good. It is just changing TV guide groups in theaterview that is the issue.

I have removed AV, changed the amount of guide data brought in to 7 days from 14 days for the guide groups and have made a test group containing a single channel with no TV guide data assigned at all, and the issue remains.

Starting a 1080P DVB-S2 channel happens pretty much immediately which surely must be more work for MC in total that changing to a guide grouping that contains a single channel with no guide data?

Do I really need to upgrade hardware just to make this issue go away?

The delay when changing groups is also exactly the same on all clients. Admittedly, these are slower hardware as all they do is run MC as clients and any recording is handled on the server, but these machines all perform well and display the exact same issue with the guide group change and take the same amount of time.

Do clients browse the guide from the server in real time or do they cache a copy of that and the library information when they connect/update?

Hi konkeydong75, I'm sorry to hear you're still noticing this issue as it's a long time you've first posted about it.
My setup is pretty the same as yours, only using a more recent PC as MC Server and has a GT1080 as primary DP out.
As mentioned into your other post, groups under TV Guide is also what I'm using. Using keywords which points to a specific smartlist.
Speed when switching amongst these groups is the same as making other types of switch over's.
FYI I'm using 2 rather old NUC's as MC clients upstairs and the group switching speed is actually pretty snap and fast.
Sorry but i wouldn't have any suggestion about your issue.
I think Yaobing, if i remember well, was included into your other/initial post, maybe he can offer you some solution or test ? P.e. loading your library setup via a backup ? In case the issue isn't hardware related ?

Hi @Mans,

Thank you for your comments.

I will continue trying things as and when I get the time - I was just hoping that others had seen the same issue and worked out what it was.

What is the source of the TV Guide data? Maybe the source XML has grown extremely large (I have no clue how to check, I don't use the TV features).
If the Guide is just filtering Smartlists, maybe you can go and open each of those Smartlists to see if they take a long time opening. With normal Media files sometimes all it takes is a few files located on an inaccessible network location, causing a 30s freeze when MC tries to access them or check for their existence. Not sure if any of this applies to TV (it likely applies to recorded TV files, but not to live TV channels).

As Mans said, Yaobing knows best. Try sending him a PM.
