What can be the reason for the slow rendering of the DLNA directory tree on the client when using a Mikrotik router?

Good afternoon! An interesting question was brought to network protocol experts and just
experienced users of the Mikrotik router.
So, I recently replaced the old router with a gigabit Mikrotik RB951G-2HnD.
Everything is fine, except for one interesting problem. I have in my local network - a PC with a
DLNA server installed (twonky) and a client for it in the form of an LG TV.
Which on the old router perfectly twisted the kintso for me for a couple of years.
But after replacing the router with Mikrotik, TV began to build a directory tree of media content,
to build a catalog, poor TV freezes for 2 minutes, when it was built on an old router in a couple of seconds. Such freezes occur every time the directory is changed to a new one, after they are built, it goes on naturally quickly through the directories until the TV is turned off.
At the same time, streaming video is perfect even - fullHD.
Mikrotik settings are default, stuck in QuickSet.
The server and client are connected via a cable.
Any ideas what could be causing this problem and how it can be fixed are welcome.

Thanks everyone for the replies.
The problem was in the TV, all other DLNA clients worked fine,
(SONY TV, desktop PC clients, mobile)
The problem was solved by simply setting Mikrotik->IP->UPnP: allow-disable-external-interface to yes .
I have no idea what this parameter is and why the DLNA client on the LG TV needed it so much.

You need to look at what is happening in Torch on the interface, if there is any tricky protocol - check the settings for it. But, logically, if your TV and computer are on the same network, then the march does not participate at all. Perhaps the matter is in setting up physics \ speed or port mode.

Well, let's try to get a finger in the sky.
0. Connect the DLNA server and TV directly using a crossover cable or a blunt switch.
1. Disable all rules in the Firewall.
2. Lock the Mikrotik port <—> TV set to 100 Mbps. Full Duplex, MTU 1500 .
3. Enable IP -> UPnP in Mikrotik
4. Disable IP -> SMB (SAMBA)
But this is of course stupid. You need to get into Mikrotik and look in the logs and other tools what is happening. I think that Mikrotik has nothing to do with it, it's all about the TV.
