MY SETUP: I have apache solr full text search enabled with dovecot. I have an inbox with about 40 subfolders. I'm using the roundcube web-based mail client. The find command is showing 15823 email files and apache solr reports the same number. I'm running a dedicated mail server with a 1 GB of ram. The solr machine is running on a separate machine with 4 GB ram.
THE PROBLEM: When I do a full text search through all my inbox and all subfolders on a single word, search results are returned in about 10 to 15 seconds. This is better than the 40 seconds or so I'm getting when I turn off the fts and fts_solr plugins but still a little disappointing.
WHAT I'D LIKE: Now, I don't expect instant search results like gmail, but getting the search results to display in less than 5 seconds would be a lot less painful that 10 to 15 seconds.
WHAT I'VE TRIED: I have reindexed the emails on solr to try to speed things upit up.
ANY ADVICE? Curious to know what response times others are seeing and if there is anything else I might try to speed things up. Maybe the number of subfolders is slowing things down?
