GOOD ALTERNATIVE! It's quit easy as alternative if no present object-caching is possible. Keep project alive! I like what seen far in Benchmark and Google Lighthouse.

The plugin moves all transients to dedicated table thus reducing wp_options size significantly. It works as expected and even another transient related plugins such as Transients Manager do work without any issues.
