I'm inclined to believe the problem is not that high up the food chain. 
Because when I query IMAP on a single folder over telnet following the 
instructions found here: 
https://doc.dovecot.org/configuration_manual/fts/solr/, imap reports 
that it's taking 3 to 4 seconds to return results:

a search text "maynez"
a OK Search completed (3.386 + 0.001 + 0.250 secs).

This particular search returns a few hundred results.

The speed of the query changed depending on whether a lot of results are 
returned. So if I search on a nonsensical word like "zyzzix", imap 
reports results nearly instantaneously:

a search text "zyzzix"
a OK Search completed (0.012 + 0.000 + 0.006 secs).

I just did a quick test. I did a search over imap over telnet with fts 
plugins turned off and with them turned on.

The search time was no better with it on than off.

So I'm thinking I got something misconfigured somewhere. It seems IMAP 
may not be using solr to fetch results. But this would be odd since I 
definitely do see a big improvements in times with fts plugins turned on 
when using roundcube.
