What are you trying to find out? It may be good to work with your partner or Aruba SE to explain your use case.
In general, your performance will decrease by limiting features. It's always a trade-off between the available 'airtime' and the single-client/multi-client overall performance. If a client connects with as many streams as possible, the data is transferred faster and your 'air' is free again for other clients. By limiting to 1x1, you will in practice end up with leaving airtime unused. Unless you have a very specific scenario where that is not the case. Also, note that MU-MIMO only works for clients that support it which is at the moment far from all clients. AirMatch/ClientMatch has the intelligence to group clients with similar capabilities to optimize this in an automated way much better than you probably can do this in a manual way, in practice. It's fun to have theoretical discussions, but for that, it is important to understand your exact use-case and assumptions. Having the discussion interactively with your partner or Aruba SE seems better than on this forum. If you end up with a conclusion and questions following that conclusion, it may be good to post it here or get it checked internally with people like Jerrod.

Subject: [AP-535/AP-555] "Forcing" 1x1:1 MU-MIMO?
Hello,
- AP-535 supports 4x4:4 MU-MIMO on 5 GHz radio
- AP-555 supports 8x8:8 MU-MIMO on 5 GHz radio
In this thread jhoward posted benchmark results from 802.11ax and 802.11ac clients using MU-MIMO for download. I assume for the clients the default settings were used, i.e.
- if a client supports 2x2:2 MU-MIMO (e.g. Intel AX200) it connects with 2x2:2
- if a client supports 3x3:3 MU-MIMO it connects with 3x3:3
Has anyone tested if overall performance increases if clients are forces to connect with 1x1:1 to the access point? Is there any setting on ArubaInstant for forcing clients to uses 1x1:1 even if they support more streams?
