OPC UA Client Sessions Limits

I am running a simulator in Python that creates 70 sessions writes to tags created on the Ignition OPC UA as a Programable Device Simulator. I have two questions:

1.- Apparently, there is a limit of about 100 sessions that are allowed to connect to the OPC UA Ignition server, but I read some forums that there is no limit by changing the "Max Session Count" on the Advanced Settings of the OPC UA Settings. I changed that number to 1000 to have more sessions available, but still get a limit of 100. Is this setting actually used, or the OPC UA server is limited forcefully to 100? I restart the ignition service all the time to reset the OPC UA server sessions and have 0 sessions connected.

2.- When I create the sessions at once, the server refuses the session, so I added a time to wait between the start of the sessions. I started with one second and had no problem, but with time (around 3 months of modifications) I now have to wait 1 minute between sessions to be started, and it is a problem, because if I want to have 72 sessions, I would have to wait >1 hour to have all sessions started. Is there some setting that I should modify or something else? Note: Also, as in question 1, I restart the ignition service all the time in order to have 0 sessions started before I run my simulator and to have the Ignition OPC UA server reset before having any client connected to it.

Thanks in advance.

It's supposed to work as of ~8.1.17 but it looks like it would require a restart before it took effect.

Why in the world are you opening 70 sessions instead of just using one?

If you're connecting from another host then this probably has nothing to do with Sessions but rather is the connection rate limiting stopping you from opening connections too quickly.

Again - why are you opening 70 connections/sessions?
