ElasticSearch 1.1.0 is slower compared to ES 0.90.3?


(dark_shadow) #1

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 notbe 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.
