      • a new multiuthreaded implementation of the javascript dispatcher has been developed
      • a set of test cases have been developed PRIOR to refactoring the dispatcher
      • a performance assessment has been carried out at the end which demonstrate the difference in performance (time response, workload being supported). Hopefully the difference will be favourable and significant. 

      This feature is timeboxed at 3fp. We hope that it will lead to a significant change in performance, even if not at a complete solution of the problem.

      NOTE: Giorgio's stance is that if we never start working on this issue it will be never fixed.

    Description

      According to the results obtained by the performance spike SP-296 we need to refactor part of the code of the frontend of WebJive (namely the code that dispatches data frames to dashboards and widgets) so that its performance is increased.

      • asynchronous code is needed
      • better ways for triggering and processing a data frame (by setting the state of the dashboard, propagating the data to the react-based components, etc)

      In addition the causes of the crashes of webjive with large dashboards and slow widgets should also investigated: we want to know with more precision under which conditions this happens.
