Hi @seoergoweb,
You can expect one additional post request with ajax to your server, after the page has been loaded. This to ensure compatibility with caching plugins. As the request is fired after the page has fully loaded, it won’t impact your user’s experience. Additionally, you can defer the script to ensure it loads last. In a future release this will be an option, right now you can do this with a caching plugin, or a mu-plugin snippet. Usually statistics scripts will load early on the page to be able to measure more bounces, which is why the defer is not default.
We have done extensive tests with performance, and use it on our own sites as well with quite a lot of traffic (really-simple-ssl.com, complianz.io). One of the advantages of self hosted statistics is that there’s no third party server involved, so it loads pretty fast.
Currently we also have agregation/archiving of data in development, with which you can choose to archive statistics data after a certain period, to limit the statistics table size.
If you have any feature requests, you can submit them here:

Let me know if you have any questions!
