How to speed up document pushing to user's machine from sync gateway?

We have very good network bandwidth for most of the users. But the data from the server is being synced down very slowly. Is there a way to improve the performance of document-pushing from the sync gateway down to the user’s machine? Any settings at the sync gateway or Couchbase Server level? Please guide


A common reason why sync gateway can be slow is it not having enough channel cache.

Whats is your biggest channel? How many documents does it have? Is it bigger than 500 docs + any deletes(tombstones)?
