In January, we upgraded Solr from version 6 to 8 skipping all versions in between.
The hardware and Solr configurations were kept the same but we still faced degradation in response time by 30-50%. We had exceptional Query times around 25 ms with Solr 6 and now we are hovering around 36 ms. Since response times under 50 ms are very good even for Auto-Suggest, we have not tried any changes regarding this. Nevertheless, you can try using Caffeine Cache. Looking forward to read community inputs as well.
