There is no magic bullet. And there's no way for anybody but you to determine how long it's going to take. There are people who have achieved over 50K inserts per second, and others who have difficulty reaching 1000 per second. Many factors affect indexing speed, including the size of your documents, the complexity of your analysis, the capabilities of your hardware, and how many threads/processes you are using at the same time when you index. Here's some more detailed info about reindexing, but it's probably not what you wanted to hear: https://wiki.apache.org/solr/HowToReindex Thanks, Shawn
