This is a simple benchmark for several javascript frameworks. The benchmarks creates a large table with randomized entries and measures the time for various operations including rendering duration.

The following operations are benchmarked for each framework:

• create rows: Duration for creating 1000 rows after the page loaded.
• replace all rows: Duration for updating all 1000 rows of the table (with 5 warmup iterations).
• partial update: Time to update the text of every 10th row (with 5 warmup iterations).
• select row: Duration to highlight a row in response to a click on the row. (with 5 warmup iterations).
• swap rows: Time to swap 2 rows on a 1K table. (with 5 warmup iterations).
• remove row: Duration to remove a row. (with 5 warmup iterations).
• create many rows: Duration to create 10,000 rows
• append rows to large table: Duration for adding 1000 rows on a table of 10,000 rows.
• clear rows: Duration to clear the table filled with 10.000 rows.
• clear rows a 2nd time: Time to clear the table filled with 10.000 rows. But warmed up with only one iteration.
• ready memory: Memory usage after page load.
• run memory: Memory usage after adding 1000 rows.
• startup time: Duration for loading and parsing the javascript code and rendering the page.

For all benchmarks the duration is measured including rendering time. You can read some details on this article. The results of this benchmark is outlined on my blog (round 1, round 2, round 3, round 4 round 5 and round 6).

Have node.js (>=7.6) installed. If you want to do yourself a favour use nvm for that and install yarn. The benchmark has been tested with node 8.4.0. For some frameworks you'll also need java (>=8, e.g. openjdk-8-jre on ubuntu). Please make sure that the following command work before trying to build:

> npm
npm -version
5.0.0
> node --version
v8.0.0
> echo %JAVA_HOME% / echo $JAVA_HOME
> java -version
java version "1.8.0_131" ...
> javac -version
javac 1.8.0_131

As stated above building and running the benchmarks for all frameworks can be challenging, thus we start step by step...

Install global dependencies This installs just a few top level dependencies for the building the frameworks and a http-server.

npm install

We start the http-server in the root directory

npm start

Verify that the http-server works: Try to open http://localhost:8081/index.html. If you see something like that you're on the right track:

Now open a new terminal window and keep http-server running in background.

cd react-v16.1.0-keyed
npm install
npm run build-prod

There should be no build errors and we can open the framework in the browser: http://localhost:8081/react-v16.1.0-keyed/

cd polymer-v2.0.0-non-keyed
npm install
npm run build-prod

There should be no build errors and we can open the framework in the browser: http://localhost:8081/polymer-v2.0.0-non-keyed/

cd react-polymer-data-table
npm install
npm run build-prod

There should be no build errors and we can open the framework in the browser: http://localhost:8081/react-polymer-data-table/
