I have a desktop application written with Spring Boot 2.7.3 (without the web server) and UI part with JavaFX. Everything is working pretty solid. But the startup time of the application is beyond 5s. And sometimes it takes more than 10s. And this is not because of the hardware as the desktop have decent specs.
To provide good user experience, I need this startup time below 1s or may be 2s
Things I have tried
- Lazy initialized beans and repositories
- Excluded some autoconfiguration classes to the best of my knownledge
Please suggest me ways to optimize this thing.
