What will happen if thousands of connections are launched simultaneously?

Launching thousands of connections simultaneously can lead to several problems:

• Server overload: The server may exhaust available resources (memory, CPU, network ports), leading to decreased performance or failure.
• OS and network limitations: The operating system and network devices have limits on the number of simultaneous connections, exceeding which will cause errors.
• Delays and timeouts: Due to high load, response times will increase, and some connections may be interrupted.

To prevent such issues, connection pools, load balancing, and limiting the number of simultaneous connections are used.
