I have a LAMP server with several WP sites (not MU). In the first site wp-piwik works well, with Tracking>Enable cache: active in the plugin config options.

In the second site enabling API cache breaks wp-piwik with a generic error (check auth token, URL and settings). this is the debug script output:

If I disable API call caching wp-piwik works as expected, here the script output:

Why?
What is the performance cost of not caching the API call?

It just a bug regarding caching: If WP-Piwik is not configured, it caches the non-configured API call and won’t work anymore. After disabling caching and triggering the API calls again, you should be able to re-enable caching without problems.

Thank you André, it is exactly as you say. I tried again and it accepts the API call caching this time.
