Hi! I using RightImage\_CentOS\_5.4\_x64\_v5.6 image for ES cluster. But I heard recently that on ubuntu (version?) it works much faster. It's true? What meaningful difference between ubuntu and centos that makes it faster if it's true? ---

Hi, I haven't tested CentOS vs. Ubuntu, but I highly doubt it makes any difference. The key parts are various ES/Lucene settings, JVM tuning and such. ## Otis Sematext in Hiring Search People World-Wide -- [Jobs](http://sematext.com/about/jobs.html) On Dec 16, 5:11 pm, Serg Pilipenko [cloun.ru...@gmail.com](mailto:cloun.ru...@gmail.com) wrote: > Hi!
