Blocking Threads Customization

SWS allows limiting the number of blocking threads powered by the Tokio runtime.

This feature can be controlled by the numeric -b, --max-blocking-threads option or the equivalent SERVER_MAX_BLOCKING_THREADS env.


We use 20 in Wasm by default and 512 in native environments (Tokio's default). See Tokio max_blocking_threads API for more details.

Below is an example.

static-web-server \
    --port 8787 \
    --root ./my-public-dir \
    --max-blocking-threads 20
