Performance Considerations - e2technologies/ViewCSS GitHub Wiki

For performance, the configuration object is lazily created and then cached so that subsequent calls with the same "class name", "class", and "style" will reuse the cached value.

The cache is reset when the dictionary object is set. If the CSS dictionary can be updated while the application is running, for example, a new version was fetched from the server, it is recommended not to reload the dictionary until the application is reloaded. This will ensure that the user experience is consistent.
