In this talk, you'll be introduced to the basic concepts of profiling Java code using perf_events (aka perf). You'll see how to collect stack traces and how to use Flame Graphs to provide a dynamic visual display for them. This, in turn, allows you to see if your code has room for improvement - and where it could be improved - in an easy and scalable way.

It doesn't matter if you are coding a one-hundred or a one-hundred thousand...

MongoDB Sharded Cluster is very well established to handle huge amounts of data across geographically separate data centers. Sharding the data across the shards evenly or specific to region/data centers based on the application requests are important. But sometimes the sharded cluster setup is not well designed, which leads to data being distributed improperly across shards so the application fails to serve the request within the...

Visualizing profiling information can be a very powerful tool for performance diagnostics, specially if we zoom right into the problem. Flame graphs were developed for this purpose and we use them on a daily basis at Percona to successfully solve complex performance issues. In this presentation, attendees will learn advanced techniques for profiling with performance and visualizing those profiles with flame graphs, as well as other...
