Tomoko Uchida commented on SOLR-3055:
-------------------------------------
I performed brief benchmark by JMeter for Solr 5.0.0 trunk and strategy 1.
There seems to be significant performance gain for n-gram based phrase query.
- Hardware : MacBook Pro, 2.8GHz Intel Core i5
- Java version : 1.7.0_71
- Solr version : 5.0.0 SNAPSHOT / 5.0.0 SNAPSHOT with SOLR-3055-1.patch
- Java heap : 500MB
- Documents : Wikipedia (Japanese) 100000 docs
- Solr config : attached solrconfig.xml (query result cache disabled)
- Schema : attached schema.xml (NGramTokenizer's maxGramSize=3, minGramSIze=2)
- Queries : "python", "javascript", "windows", "プログラミング", "インターネット", "スマートフォン"
(japanese)
- JMeter scenario : execute each 6 queries above 1000 times (i.e. perform 6000
queries)
- JMeter Threads : 1
To warm up, I performed 2 times JMeter scinario for both settings.
2nd round results are:
|| Solr || Avg. response time || Throughput ||
| 5.0.0-SNAPSHOT | 7msec | 137.8/sec |
| 5.0.0-SNAPSHOT with patch-1 | 4msec | 201.3/sec |
