What kind of search response time are you setting with solr full text search?

[Steve Dondley]

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?
