Alfresco Solr Memory
Solr is Alfresco’s repository search engine. It is common for Solr to get slower as more documents are indexed. After all, the larger the index, the more time it is going to take to navigate the index to find a document. However, Solr should not be unbearably slow. Solr stores the location of every item in the index or index segment files. As the Alfresco repository grows larger, so do the index files. In a large repository, index segments may be gigabytes big To find the documents related to a word, Solr has to search in the index files. As you know, reading from disk is a slow operation, so Solr tries to keep as much data as possible in its memory caches.
