All applications are built in ESM format and keepAliveTimeout: 0 is set.

The shorter the cold-start time, the better the frameworks are suited for serverless technology. So, the results of a cold start are as follows:

For now, this benchmark is run manually, for example:

node dist/ditsmod/main.mjs
# OR
node koa.mjs
# OR
node dist/nestjs/main-express.mjs
# ...

See package.json for more examples with start script.

From first terminal:

npm run ditsmod

"Hello, World!" performance comparison for web frameworks:

• ditsmod
• fastify
• koa
• express
• nestjs-express
• nestjs-fastify
• hapi

From second terminal:

wrk -t4 -c20 -d30 -H 'Connection: close' http://localhost:3000/hello

You can also check the work of Ditsmod and NestJS with controllers that are created "per request". To do this, request for the path /hello2, for example:

wrk -t4 -c20 -d30 -H 'Connection: close' http://localhost:3000/hello2
