Question:
Why constant updates slow down SOLR performance even if I am not executing Commit? I just noticed this... Thead dump shows something "Lucene ... Clone()", and significant CPU usage. I did about 5 mlns updates via HTTP XML, single document at a time, without commit, and performance went down, 100% CPU... After Commit/Optimize it is stabilized, 0.5 - 2 seconds per page generation (100 facets + 100 products), 15%-25% CPU: filterCache class: org.apache.solr.search.LRUCache version: 1.0 description: LRU Cache(maxSize=2000000, initialSize=1000000) stats: lookups : 109294990 hits : 107637040 hitratio : 0.98 inserts : 1658092 evictions : 0 size : 879637 cumulative_lookups : 341225983 cumulative_hits : 337721881 cumulative_hitratio : 0.98 cumulative_inserts : 3504573 cumulative_evictions : 0 Performance of SOLR itself is good/acceptable (even with huge facet distribution), but it goes down when I do a lot of updates (without commit/autocommit) Thanks, Fuad http://www.tokenizer.org
