Unfortunately we don't have historic comparable perf benchmarks between versions. But my guess is that the improvements in the underlying Lucene library between 4.5 and now will give you both a smaller index and various speedups. Check the graphs for your typical use case here https://home.apache.org/~mikemccand/lucenebench/
The best you can do is to perform some benchmark on a single-node 4.5 instance with your schema and data, and compare with a single-node 8.11. It should not take too long to convert the schema file to be compatible with 8.x. The challenge is to create the query benchmark in a way that lets you compare.
