Partner – Jmix Haulmont – NPI EA (cat= Architecture)
Building or modernizing a Java enterprise web app has always
been a long process, historically. Not even remotely quick.
That's the main goal of Jmix is to make the process quick
without losing flexibility - with the open-source RAD platform
enabling fast development of business applications.
Critically, it has very minimal impact on your server's
performance, with most of the profiling work done separately - so
it needs no server changes, agents or separate services.
Simply put, a single Java or Kotlin developer can now quickly
implement an entire modular feature, from DB schema, data model,
fine-grained access control, business logic, BPM, all the way to
the UI.
Jmix supports both developer experiences – visual tools and
coding, and a host of super useful plugins as well:

Slow MySQL query performance is all too common. Of course
it is. A good way to go is, naturally, a dedicated profiler that
actually understands the ins and outs of MySQL.
The Jet Profiler was built for MySQL only, so it can do
things like real-time query performance, focus on most used tables
or most frequent queries, quickly identify performance issues and
basically help you optimize your queries.
Critically, it has very minimal impact on your server's
performance, with most of the profiling work done separately - so
it needs no server changes, agents or separate services.
Basically, you install the desktop application, connect to your MySQL
server, hit the record button, and you'll have results
within minutes:
