Flame graph profiles so you can compare what is using CPU time when working with variants [profiles.zip](https://github.com/user-attachments/files/26445694/profiles.zip) Variant rebuild is expensive, I've got a minor (and will keep package private) tweak to VariantBuilder to allow VariantStringConverter to add a Binary as a string to the variant without converting it to a string en-route, which would save a lot of needless string creation. Variant.getFieldAtIndex() is pretty expensive too. -- This is an automated message from the Apache Git Service.
