Disable Nagle Algorithm

[dom96]

Interesting, two questions:

• Is this what benchmarks typically do in TechEmpower?
• Did you do any testing to see this benchmarking better?

Is this what benchmarks typically do in TechEmpower?

• As commented, h2o uses by default.
• Go uses SetNoDelay by default. https://github.com/golang/go/blob/2ebe77a2fda1ee9ff6fd9a3e08933ad1ebaea039/src/net/tcpsock_posix.go#L144
• Rust's hyper doesn't set by default, but enabled in the framework benchmarks https://github.com/TechEmpower/FrameworkBenchmarks/blob/73eb2abec4e5c594e40812250ebe061234fe9473/frameworks/Rust/hyper/src/server.rs#L44

In addition, Nginx enables this option by default. https://nginx.org/en/docs/http/ngx_http_core_module.html#tcp_nodelay

Did you do any testing to see this benchmarking better?

Not yet(stable benchmark is so hard!). However, 7-8 years ago, I tried to optimze nginx.conf at work and it's always good to turn tcp_nodelay on, which is enabled by default.
