I am playing with an index that is sharded many times, between 64 and 128. One thing I noticed is that with replication set to happen every 5 minutes, it means that each slave hits the master at the same moment asking for updates: :00:00, :05:00, :10:00, :15:00 etc. Replication takes very little time, so it seems like I may be flooding the network with a bunch of traffic requests, and then goes away.
I tweaked the replication start time code to instead just start 5 minutes after a shard starts up, which means instead of all of the slaves hitting at the same moment, they are a bit staggered. :00:00, :00:01, :00:02, :00:04 etcetera. Which presumably will use my network pipe more efficiently. Any thoughts on this? I know it means the slaves are more likely to be slightly out of sync, but over a 5 minute range will get back in sync.
