ElasticSearch 1.1.0 is slower compared to ES 0.90.3 ?

dark_shadow
Hi,

I was using ES 0.90.3 in production earlier but after moving to ES 1.1.0, it is taking a longer time for a search query to fetch results ? I'm using same mapping and same search query. The only difference is that I'm using jdk 1.6. Should I migrate to 1.7 ? Also, how does sharding and replica affect searching time ? Can anyone please tell me the major factors which affect the search time ?

Thanks

You should *not*be using < JDK 1.7.
Upgrade to at least 1.7u25, preferably 1.7u55, and Oracle not OpenJDK.

Are you sure about jdk 1.7 ? My guess is one should use jdk 1.7 with ES 1.2.0. Also, earlier with ES 0.90.3 it was working fine. How can jdk version affect the search query time ?

The < means less than, ie you should not be using less than 1.7.

There are a lot of bug and performance fixes in later versions of java, that will impact the performance and stability of any application that uses it.
