Hi Folks; This week we will make a pre-production version of our system. I've been askng some questions for a time and I gor really good responses from mail list. At pre-production and test step:
* I want to measure how much RAM I should define for my Solr instances, * I will try to make some predictions about how much disk space I will need at production step. * Maybe I will check my answer for that question: which RAID to use (or not use) etc. For that questions I got answers from mail list and I have some approximations about them. Also I know that it is not easy to answer such questions and I should test them to get more accurate answers. My question is that:: What do you suggest me at pre-production and test step? * i.e. give much more heap size to Solr instances to calculate RAM * use solrmeter to test qps for your cluster * use sematext or anything else for performance monitoring etc. I need some advices what to test, calculate, measeure etc. Also there was a question about Codahale metrics and Graphite. You can advice something about that too. PS: I use Solr 4.2.1 for tests but if Solr 4.3 becomes ready (if it is tagged at repository) I will use it.
