Install and build

git clone --depth 1 https://github.com/ditsmod/vs-webframework.git
cd vs-webframework
npm i
npm run build

All applications are built in ESM format, keepAliveTimeout: 5000 is set, and generation of additional headers is disabled.

Cold start

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:

framework	result, ms
express v4.19	4
koa v2.15	4
restify v11.1	8
ditsmod v2.52	18
fastify v4.26	22
hapi v21.3	23
nest v10.3 + fastify	45
nest v10.3 + express	107

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.

Run benchmarks

npm start
ab -n 20000 -c 10 localhost:3000/hello
# OR
wrk -t1 -c10 -d5 -H 'Connection: close' http://localhost:3006/hello

Here you need manually changes port in the range from 3000 to 3007.

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

• Fastify
• Ditsmod
• Koa
• Restify
• Express
• Nestjs + Express
• Nestjs + Fastify
• Hapi

The following command will allow you to view the status of running programs:

npx pm2 l

If you run this command immediately after running the benchmark, in particular you will see how much memory each of the applications is consuming.

Interesting information is in the cpu and mem columns. Also in ↺ column you can see number of restarting the applications.

In addition, 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 -t1 -c10 -d3 -H 'Connection: close' http://localhost:3006/hello2

Stop webservers

npm run stop
