[pgAdmin] Startup speed improvements + identified bottlenecks (related to issue #9770) - Mailing list pgadmin-hackers

Hi,

I have been looking into pgAdmin desktop startup performance and identified multiple bottlenecks in the startup path. A quick summary:

- Synchronous DB migrations blocking startup
- Redundant table validation on every launch
- Eager loading of all modules/blueprints
- Driver/auth registries loaded upfront
- 1s polling delay in backend readiness detection
- Sync logging during startup

As a first step, I have implemented a small fix for the polling issue (adaptive polling instead of fixed 1000ms), which improves responsiveness without touching backend logic. Also, the startup feels noticeably slower than expected due to the amount of synchronous work being done upfront, which is what led me to dig into this.

Before opening a PR for this change, I wanted to check if this approach is acceptable.

This is part of ongoing work around issue #9770, and I plan to address the other bottlenecks incrementally.

Thanks and regards
