How many concurrent web client connections does the web client server support ?

I have a plan to develop the wincc oa server project with web client server.
And I want to check the maximun number of concorrent web client connections.

My operation system enviroment is the below:

- Process: 2.4GHz 2 Process
- CPU Core: 64 Core or more
- Memory: 64Ghz or more
- Disk: SAS SSD 1T * 4 (RAID 10)

Please feedback to me about your experiences with regard to web client approach.

The documentation contains the following recommendations:

This configuration is recommended for 35 ULC UX connections per web server with a medium amount of dynamic panel elements. For high dynamic panel content the number of ULC UX clients must be reduced accordingly to the increased traffic.

• Having a high number of dynamic elements (animations, color changes, etc.) inside of the panels should be avoided as they cause an increased CPU load on server and a higher traffic load on the network.
• The WinCC OA project and the WinCC OA web server should be deployed on different computers to avoid influences on the WinCC OA server project (Event, Data, etc) due to higher loads and CPU usage of the ULC UX (e.g. due to a high number of client connections). If the web server and the project cannot be split to different machines a corresponding number of RAM and CPU capacities are required.
• When using SSO it is recommended to use a redundant Active Directory to provide higher availability of the service.
• The recommended number of ULC UX connections is based on the assumption Windows is used as web server operating system. When using a Linux distribution as operating system for the web server the recommended connection count increases from 35 to 55 connections per web server.
