I am facing some performance issues on my Solr Installation (3core server). I am indexing live twitter data based on certain keywords, as you can imagine, the rate at which documents are received is very high and so the updates to the core is very high and regular. Given below are the document size on my three core.
Twitter - 26874747 Core2 - 3027800 Core3 - 6074253 My Server configuration has 8GB RAM, but now we are experiencing server performance drop. What can be done to improve this? Also, I have a few questions. 1. Does the number of commit takes high memory? Will reducing the number of commits per hour help? 2. Most of my queries are field or date faceting based? how to improve those? Regards, Rohit
