Run a query on both old and new with &debugQuery=true on your query request and look at the component timings for possible insight.

Indexing performance slight degradation over 1.3 For Indexing we use our custom scripts that post xml over HTTP. Any thing that I might have missed . I am thinking that this might be due to new Tiered MP over LogByteSize creating more segment files and hence more the Query latency .We are using Compound Files in 1.3 and I have set this to true even in 3.6.1 ,but results in more segement files On optimizing the query response time improved beyond 1.3 .So could it be the MP or am i missing something here . Do let me know Please find attached the solrconfig.xml Regards Sujatha
