Every 2 months, there is a WordPress Meetup Hasselt. This time we did a little experiment: We combined a talk about Website Performance with a hands-on session. This gave us an opportunity to put the new knowledge into practice.
On beforehand we asked all participants to bring their laptops so they could work on any of their own websites. If there was no website available, a test-site was available to work with.
The full report of the meetup is available on the website of WP Belgium.
