Igniters, I've just published an article that describes one of the reasons for why an Ignite cluster can underperform. It's reviewed how a selection of proper Ignite APIs can put less pressure on the network and proliferate the performance: https://www.gridgain.com/resources/blog/why-my-in-memory-cluster-underperforms-negating-network-impact
Let me know what you think. Suggest any other themes you would want to be laid out. Btw, our community member Denis Mekhanikov is doing a webinar about co-located computations in Ignite tomorrow, join him to learn more about this area: https://www.gridgain.com/resources/webinars/distributed-computing-apache-ignite - Denis
