Performance comparison for different versions of solr

["Chang, Yanlei (Charley)" <yl...@telenavsoftware.com>]

Hi solr support,

  Recently we plan to upgrade solr in our project from 4.5.0 to a newer version, the latest version we can use is 8.11.2. I want to know the performance comparison for different versions of solr, I can not get useful info in the release notes, could you help me to find the related info, We want to know if the new version has a better performance.

Thanks
Charley

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.
