Tips on determining servers per machine?

I have just launched my title this week! :)

I am hosting servers on PlayFab and trying to determine the number of servers per machine I should use.


About my game:

- Made with Unity and Photon Bolt

- 6 player matches

- <5 minute battle arena matches

What I am currently doing:

- Hosting 6 servers per Av2 machine with 1 core.

Problem:

After 3+ servers are active, the games begin to feel laggy


What I have done:

Profiling my server build in Unity I found my ram usage to always be <200mb.

Since Photon Bolt requires 7 ports, I thought I might be able to host 8 servers / Av2 1 core machine (since 8*7 = 56, 56 < 60 the max ports available?) and my ram usage should not go above 1.6 GB. This doesn't seem to be the case.

I am unsure if I should focus on optimizing my networking/CPU performance or switch the PlayFab machines I am using.

Does anyone have any suggestions?

Is there a way for me to monitor the PlayFab machines performance?

How can I determine the optimal # of servers/machine?

Thanks!

Josh

To activate the performance monitor, you could use the CreateBuildWithManagedContainer API and specifying InstrumentationConfiguration parameter with a list of processes to monitor on the machine. After the build creation has been created and has standing by servers, you can find the csv files that contain the performance metrics collection output in the shared content folder on each VM. Please refer to this document: Collecting performance metrics on Windows multiplayer servers (experimental) Then you could adjust the servers/machine to find out the which gives the best performance.

@Rick Chen, could you please update the link for "Collecting performance metrics on Windows multiplayer servers (experimental)". It is returning a 404. Thanks!
