Thanks for the report! Could you please try if using a newer R8 version has any effect, see https://r8.googlesource.com/r8/+/refs/heads/master/#replacing-r8-in-agp (just in case this is an issue with R8 which is fixed in newer versions).
Do you know if there is some way to find out why R8 performance has decreased for Gson or if there is some way to make R8 output profiling data about where it takes the most time?
Since you already have VisualVM connected, could you please try enabling the Sampler and share the results (and the R8 version you are using)? Maybe that in combination with the R8 obfuscation mappings (see https://r8.googlesource.com/r8/+/refs/heads/master/#obtaining-prebuilts, r8lib.jar.map) could help at least narrowing it down.
Maybe it would also be worth asking on the R8 mailing list mentioned at https://r8.googlesource.com/r8/+/refs/heads/master/#getting-help.
