Well, before Etsy switched to Solr we were using postgres tsearch2, and by the end of that search response times were in the 90 second range. And at the time replication wasn't part of postgres so we had a hacked up buggy in-house replicator.

And we replaced sixteen extremely beefy postgres slaves with four commodity solr boxes with plenty of headroom to spare.

(Of course we now have more than four solr slaves.)
