Transcript

1. 1 Everybody loves Benchmarks A quick show of Python HTTP client performance. Nickolas Grigoriadis
2. 2 We all love Python But a common complaint is it is slow. Especially for HTTP requests.
3. 3 Common mistakes Create a new “session” for each request: requests.get(...) Instead do: session = requests.session() # Now re-use session session.get(...)
4. 4 Benchmarks • Done on my old i5-630u notebook. • Single process. • Against Apache (because I could turn HTTP/1.1 pipelining on/off) • Inside an Alpine-linux Docker container. https://github.com/vibora-io/benchmarks/pull/5
5. 5 Benchmarks! - sync requests requests (opt) urllib3 urllib3 (opt) PyCurl PyCurl (opt) 0 2000 4000 6000 8000 10000 12000 HTTP/1.0 — 1 HTTP/1.1 — 1
