Ahh MCL not MC. That bug report is much closer to this problem but still not quite.
The users in MCL-5294 seem to be using a batch script, command line switch or junctionpoint to change the game directory. Im not.
I'm trying to enter a UNC path into the Launcher options. Additional Screenshot attached. This stopped working at v2 of the Launcher
At first i thought this was related to DFS but further tests show it actually effects any UNC path. So any network path you enter, will not persist. It now has to be a local path or mapped drive.
Ubuntu VM running on a AM3+ FX 6300 Host. The VM has 2 cores allocated and 3GB ram. We mainly play locally over LAN
Its been running for several years now, running various versions as they come out. When we moved to 1.13, we created a new world, and then the lag started.
We see classic "rubber banding" lag, and the server states it is lagging behind.
I increased the VM allocation of virtual cores to all 6, it has had some effect but it is still very laggy. The server even stopped at one point today as the lag exceeded 60 seconds!
We've only had 3 players in this server at any one time so the specs should be perfectly suitable, but its not.

MCL-5500
"
MC-5294-Low Altitude Superflat worlds Create incomplete strongholds."No, this is a problem with entering a DFS path in the new launchers "Game Directory" variable.
Problem still persists in version 2.0.1003 of the launcher. It just will not accept a unc path.
Screenshot attached.

I too am having the same problem.

I've found giving my server more memory has helped a lot. More of a workaround than a fix, but at least its playable.
Edit: Its a VM with two 3.52Ghz cores, and has 5Gb RAM assigned. This seems to support about 2-3 players before we see any noticeable lag
I start the server with the following switches:
-Xmx3G -Xms1024M
