Hi. I am facing poor write performance due to insufficient number of commit proxy processes.

According to [Configuration — FoundationDB 7.2](https://apple.github.io/foundationdb/configuration.html), “the default value for commit proxies and log servers is 3”. However I can see only one process having the role “Commit Proxy”:

When I try to increase the number of commit proxies `configure commit_proxies=2`, fdbcli status command returns `Desired Commit Proxies =2` but the actual number of commit proxy processes remains 1.

I am running FoundationDB 7.1.33  
In my configuration there are three stateless processes, three transaction processes and many storage processes (6-18).

The only way to increase the number of commit proxies seems to be setting more than six stateless processes, then more than 1 commit proxy processes are started.

Is this a bug or a normal behaviour?

Thanks!

Because nobody has answered my question, I consider the current fdb behavior as a bug and I submit [a PR](https://github.com/apple/foundationdb/pull/10411) that fixes it.
