According to the documentation for blocking operations, I use synchronous functions:
import time
from fastapi import FastAPI
app = FastAPI()
@app.get(path='/index')
def index():
time.sleep(2)
return 'true'
uvicorn main:app --reload
But on testing, I see that the requests are executed sequentially and not in parallel:
ab -n 2 -c 2 http://127.0.0.1:8000/index
Server Software: uvicorn
Server Hostname: 127.0.0.1
Server Port: 8000
Document Path: /index
Document Length: 6 bytes
Concurrency Level: 2
Time taken for tests: 4.021 seconds
Complete requests: 2
Failed requests: 0
Why it happens? Shouldn't they run in parallel?
