PoB Performance Optimization

Is your feature request related to a problem?

There are a couple areas within the client that I've noticed perform far less than ideally:

• Loading a build for the first time
• Skills: Loading the support gem list when you click a new Gem name slot

These are the two big ones I can remember offhand. (Edit: Oh, and starting the program could be faster.)

Describe the solution you'd like

Faster performance. There is surely room for improvement here. (Edit: e.g. better or added pre-loading/caching.)

Describe alternatives you've considered

No response

Additional context

For context I'm running Win10 on a gaming desktop Ryzen7 1700 8-core, 16gb ram, GTX 1060. Most everything else in PoB (and other software) is very snappy.

Start by profiling the client workflows named in the issue: first-time build loading, opening a new gem name slot to load the support gem list, and program startup. Compare their current timings and identify the relevant entry points before proposing a focused scope. Done should mean a measured improvement in the selected workflow without regressing normal client behavior.
