K91757375 Oneconnect with one Pool member

Hello community,

I hope you someone can explain me the following statement made by F5.

Found under: https://my.f5.com/manage/s/article/K91757375

Cause

The OneConnect feature works with HTTP Keep-Alives to allow the BIG-IP system to minimize the number of server-side TCP connections by making existing connections available for reuse by other clients. "Hence, applying a OneConnect profile to a virtual server with only one pool member is considered a bad configuration since there will be only one TCP connection in the server-side of the connection."

I don't understand the statement "only one TCP connection" in server-side connection. Is that related to "one connection" per (external) client or for all external clients (what I can't believe)?

It sounds like "oneconnect" makes not sense with only one pool member because oneconnect hasn't not effect in this case. But for my understanding oneconnect should also reduce server-side connections with only one pool member ...right? If a connection is marked for reuse (create by first client), second external client can use that. Otherwise the second client will create a new server-side connection (if the first connection is still in use). After that there are two server-side connections (against the statemant "only one TCP connection").

What is right or wrong? Thanks
