Hello Deepak, We are not querying when indexing is going on. Whatever CPU graph I shared for 6.2.1 and 6.5.1 was only while we do batch indexing. During that time we don't query and no queries are getting executed. We index in a batch with a rate of around 100 documents / sec. And it's not so

Regarding query times, we couldn't see big improvements. Both are more or less same. Our main worry is that, why CPU usage is so high in 6.5.1 and above ? What's going wrong ? Is any one else facing this sort of issue ? If yes, how to bring down the CPU usage? Is there any settings which we

The metrics code added in 6.4 cause a big performance problem. I believe that was fixed by 6.5.1, but there might be some lingering issues. See: https://issues.apache.org/jira/browse/SOLR-10130 wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Apr

Do you see a performance improvement in your 'Query Times' (6.2.1 vis-a-vis 6.5.1)? Deepak "Please stop cruelty to Animals, help by becoming a Vegan" +91 73500 12833 deic...@gmail.com Facebook: https://www.facebook.com/deicool LinkedIn: www.linkedin.com/in/deicool "Plant a Tree, Go Green"

It would help if you can trace it down to a version change. Do you have a test system and start with 6.3.0 as next version above 6.2.1 to see which version change is making you trouble? You can then try 6.4.0 and 6.5.0 next. And after that go into subversions. Regards, Bernd Am 16.04.2018 um

Hi Bernd, We didn't change any default settings. Both 6.2.1 and 6.5.1 is running with same settings, same volume of data, same code, which means indexing rate is also same. In Case of 6.2.1 CPU is around 60 to 70%. But in 6.5.1 it's always around 95%. The CPU % in 6.5.1 is alarming for us and

As a first guess I would say that you have much higher GC activity which causes much higher CPU usage. Why do you have much higher GC activity? Any GC settings changed? Have you tried increasing heap size? Regards Bernd Am 16.04.2018 um 06:22 schrieb mganeshs: > Solr experts, > > We found
