Benchmarks the performance of a nea platform using a rust request handler compiled as one compilation unit.
The examples can be run with cargo. For performance benchmarking, it is essential to limit the number of log messages that is printed (the lock on stderr is very contested) by setting the RUST_LOG=error environment variable for the command.
# a debug build that prints many log messages
cargo run --bin send-static-file
# only print error log messages; used for benchmarking
RUST_LOG=error cargo run --release --bin send-static-file
Even when only error messages are configured, some log messages may be visible. These are printed before main runs and configures the log level. On linux, this is the expected output:
> RUST_LOG=error cargo run --release --bin send-static-file

For performance benchmarking the siege tool can be used
> siege -c 4 127.0.0.1:8080
** SIEGE 4.0.4
** Preparing 4 concurrent users for battle.
The server is now under siege...^C
