Commits aging over 6 years. Repo is not maintained at all. Is there any production ready version of this thing?

Redis?

How does it compare with LMDB?

LMDB is a fundamentally different design. Basically memory mapped B+ tree.

SILT is more algorithmicly comparable to Rocks/LevelDB. Data ages and is transformed into more and more compacted storage.

I would love to know the design and performance difference between this and redis.
