This is caused by the *fix* 
<https://github.com/couchbase/couchbase-lite-ios/pull/1919> to reduce 
memory usage during the pull replicator. The fix applies the pause logic to 
gradually load changes instead of loading all at once. It is possible that 
this could cause the performance degraded. I have 
created https://github.com/couchbase/couchbase-lite-ios/issues/1980 to 
track the issue.
