I hosted a workshop along with Guillermo at the JBCNConf 2016. The materials are online at GitHub for your perusal. The abstract contains info about the contents and there are instructions in the repository. Questions, comments and corrections are very welcome.
The workshop covered some concurrency examples from the (too) many other topics discussed in the performance talk I gave a couple of weeks earlier at the BCNJUG Meetup. Feel free to check out the slides at Slideshare or just download the pdf.
