Improve Performance of MC
konkeydong75:
Hi @zybex,
The TV guide data is an XML file that is generated every 24 hours on another internal (non MC) server and copied down to the MC server where it is stored locally.
The XML contains 14 to 15 days of data and across all channels is around 65-70MB.
The guide is just filtering on smartlists and when not in theater view the smartlists open immediately.
All data is held locally on the MC server itself for images, music, video and recorded TV, so there should be zero requests for remote media made by the server for any media or guide information unless something is being streamed and streaming starts pretty much instantly.
This is a real head scratcher for me.

Since the XML is generated on a different machine perhaps there are some references to files on that machine. Maybe try opening the XML in Notepad++ and search for "\\".
If you're more technically inclined you could inspect what happens when you switch the Guide Group with tools like Process Monitor or Wireshark. Any network accesses will show up there. You can also check if the problem is I/O or CPU limitations with Windows own Resource Monitor.

The XML is generated using pure PHP on a linux system with no reference to any UNC path. I have double checked and there are definitely no instances of \\ in the file.
There is nothing really of note performance or network wise whilst changing groups. All groups have logos assigned to the channels, and after a group has been switched nothing seems to happen, but as you scroll down the group, the odd call seems to be made to external TV guide data providers for missing logos, although this has zero performance effect on scrolling down the grid of channels in the group, it is just changing groups where it seems to hang for a few seconds.
I don't know whether the skin/theme can have any effect on the issue I am seeing? I use Rapier Fusion but have tried switching back to the built in ones and it has made no difference.

No idea if it will help in your case, but Yaobing has done some work on MC30 to speed up channel changes. You might wait for MC30 to see if it helps.

Thanks @JimH,
Have already bought the license upgrade so waiting for this drop!
I will definitely try it out when it is released.
