You're welcome @Petr Janda .

Our Friendica server is not located in Europe. So the speed might not be as fast as other servers that are located in Europe. Have a look here and see which Friendica server is near you: friendica.fediverse.observer/

You're more then welcome to try this server and see if Friendica fits your needs. Friendica is similar to Mastodon but is more suitable for blogging rather micro-blogging. See here: friendi.ca/

Best of luck and enjoy the fediverse 🙂
