Use case: Polymer vs LitElement based components benchmarks

[web-padawan]

Hi, I have a question about using this tool for our purpose at Vaadin.

We would like to setup a sample app similar to shack for using in benchmarks test.
But what we need is not to test against older commit, but agains the older version.

So we'd like to test LitElement-based app agains Polymer-based app.
Both apps would be implemented using exactly the same components.

Is this doable with tachometer at all (using another app as baseline)?

@aomarks I would appreciate any advice on this.

Hi @web-padawan -- you can definitely do this! Actually we have a repo set up at https://github.com/PolymerLabs/benchmarks that does exactly this for 3 implementations of shack done in Polymer 3, LitElement, and a hand-rolled lit-html without custom elements:

git clone git@github.com:Polymer/benchmarks.git polymer-benchmarks
cd polymer-benchmarks
npm install
npx tachometer --config shack.json

It sounds like you could use a similar setup to this for your app. LMK if you need any help setting it up or interpreting the results.

(Here are our results on shack, by the way):

Thanks! This is exactly what I need 🙂
Closing, will ping you if we have any questions.
