Question
A web application server farm has the following configuration:
- 16vCPU
- 128GB of memory
- 512GB of local storage
The performance-testing team reports the web application farm is unable to process requests beyond 5,000 concurrent connections. Which of the following should be performed?
Options
- AReview the memory capacity parameters in the web server
- BRestart and redeploy the application.
- CRestart the performance-testing tool.
- DReview the application configuration

Why each option
When server hardware resources are sufficient but a hard connection ceiling is hit, the bottleneck is almost always a configurable software parameter within the application or web server.
128 GB of memory is substantial for a web application farm; memory capacity is not the limiting factor when a hard concurrent-connection ceiling is reached.
Restarting and redeploying the application does not change any underlying configuration parameters and would not raise the concurrent connection ceiling.
Restarting the performance-testing tool does not affect the application's ability to process connections and would not resolve a server-side throughput limit.
Web server platforms and application frameworks enforce connection limits through configurable parameters such as MaxClients, thread pool size, or connection queue depth. With 16 vCPUs and 128 GB of RAM the hardware is not the constraint, pointing directly to a software-level cap that must be reviewed and tuned in the application configuration. Adjusting these settings - such as worker process limits in IIS or MaxRequestWorkers in Apache - allows the farm to handle more concurrent connections.
