    Description

      After following change in ns_server the failover  time increased from 110ms to 200+ ms:

      https://github.com/couchbase/ns_server/commit/bed1e6ea9959c99e9cf4cb6942a236be4c7702d1

      See logs attached.

      There was another failover time increase between 2864 and 2943. So total regression is about 500/600ms . I'll update the ticket as soon as I track that one as well.
