Flask - Performance Optimization

Given the command gunicorn -w 3 -b 0.0.0.0:8000 myapp:app, what will happen when you run it?

AGunicorn will start 3 worker processes and listen on all network interfaces at port 8000

BGunicorn will start 1 worker and listen only on localhost at port 8000

CGunicorn will start 3 workers but listen only on localhost at default port 5000

DGunicorn will fail because the binding address is invalid

Step-by-Step Solution

Solution:

Step 1: Analyze the command options
The -w 3 option sets 3 workers. The -b 0.0.0.0:8000 binds the server to all interfaces on port 8000.
Step 2: Understand the effect of binding and workers
Binding to 0.0.0.0 means accessible from any network interface, and 3 workers allow handling multiple requests concurrently.
Final Answer:
Gunicorn will start 3 worker processes and listen on all network interfaces at port 8000 -> Option A
Quick Check:
-w sets workers, -b sets bind address = A [OK]

Quick Trick: -w sets workers, -b sets bind address and port [OK]
