Come and hear about some of the work we have done to optimize the collaborative performance of Collabora Online recently. See how an improved mix of tils compression algorithms and AVX acceleration improves both time and bandwidth. See the impact of profiling, tons of flamegraphs, and catch the excitement of making code simpler, faster and better for users simultaneously. See too some of our recent usability optimizations: the easy little features around the UX that cumulatively make life more pleasant - and the people that have implemented them. Finally see how you can get involved with the fun.
