Debug an async summariser that is no faster than the sequential version

import asyncio, requests

async def summarize(text):
    resp = requests.post(URL, json={"text": text}, timeout=30)   # about 2 s per call
    return resp.json()["summary"]

async def main(texts):
    return await asyncio.gather(*(summarize(t) for t in texts))

asyncio.run(main(texts))
