    The announcement of the event caused unprecedented excitement, the hall was completely full. The unusual format (usually meetings are a report or reports on some general topic) probably also fueled interest. It was recommended to take laptops and preliminary preparation instructions were sent before visiting.

    Alex before the meeting. Andrey Kogun traditionally welcomes the participants, recalling the upcoming conferences and announcing his own report at JPoint 2018 . In the first part, an excursion into profiling Java applications was made with an overview of the features of Java Flight Recorder

    and Java Mission Control . The application available on GitHub was used as a test subject . In the second part, the demonstration was continued. The material is extremely useful both for a less prepared audience (as a review audience) and for an advanced one (presentation of more complex cases with qualified comments). The opportunity to ask questions and get answers to them (during the break or at the end of the meeting) turned out to be very popular. At the end of the meeting, Aleksey mentioned the Efficient Profiling of Java Applications training course , which he plans to read on May 21-22, details here . Link to the presentation . Photos will be available soon in VK and
