Very slow when rendering the registers / stack / code / threads / trace (takes around 5 seconds on break)

bash-3.2$ lldb --version
lldb-1403.0.17.67
Apple Swift version 5.8.1 (swiftlang-5.8.0.124.5 clang-1403.0.22.11.100)
Other than the slowness this will be extremely useful if it gets faster !
Thanks for the report.
We have identified the cause of the slow down and optimized our calls to the LLDB API to speed up the rendering of the registers in PR #7 and have now merged into main.
Much appreciated !
