server/client between 2 PCs

The example SimpleTCP client/server.vi work fine, when server is  a note PC, and client is a desktop PC. But when server is the note PC and client is the desktop PC, speed is very slow.  I have to wait 20 seconds until data changes. Both PCs are connected to the same hub in my home.

I tested a client/server exe.  The result is almost symmetric. Therefore, I believe the above asymmetry is due to LabVIEW enviroment. What is the reason for the asymmetry?

By the way, the desktop instals LV2014, the note instals LV2019(evaluation).

 To demonstrate the asymmetry, I have prepared a pair of client.vi and server-A.vi.

If I put the server-A.vi on the desktop PC, and the client.vi on the note PC, responce takes a few seconds. But, if I exchage the vis, responce is immediate. 

 I have found a symmetric server-B.vi. In this case, responce are both immediate.

 I hope someone explains the reason why server-A is asymmetric and server-B.vi is symmetric.
