Solr experts,

We found following  link
where its mentioned like in 6.2.1 it's faster where as in 6.6 its slower.

We are also facing same issue...with 6.2.1 in our performance environment
and we
found that CPU usage is around 60 to 70% where as in 6.5.1 it was always
more than 95%

Settings are same and data size and indexing speed remains same. Pls check
the  JVM snapshot
when we index using 6.2.1
Following is the  snapshot
taken with 6.5.1

Is there any reason why such a huge difference with CPU usage patterns
between 6.2.1 and 6.5.1 ?

Can we do something in 6.5.1 to make it as 6.2.1? Because we don't want to
downgrade to 6.2.1 from 6.5.1.

Let us know your thoughts on this.

Thanks and Regards,
