Linux Kernel vs. DPDK: HTTP Performance Showdown
Hi talawahtech. Thanks for the exhaustive article.
I took a short look at the benchmark setup (https://github.com/talawahtech/seastar/blob/http-performance...), and wonder if some simplifications there lead to overinflated performance numbers. The server here executes a single read() on the connection - and as soon as it receives any data it sends back headers. A real world HTTP server needs to read data until all header and body data is consumed before responding.
Now given the benchmark probably sends tiny requests, the server might get everything in a single buffer. However every time it does not, the server will send back two responses to the server - and at that time the client will already have a response for the follow-up request before actually sending it - which overinflates numbers. Might be interesting to re-test with a proper HTTP implementation (at least read until the last 4 bytes received are \r\n\r\n, and assume the benchmark client will never send a body).
