I've a cluster where the nodes are far apart geographically, so there is high network latency between the nodes. In such a case, I find the snapshot install from the leader to follower to be pretty slow for large datasets.

When I increase the FLAGS_raft_max_byte_count_per_rpc value, the trasfer became much faster.

1. Are there any other flags that I can tweak to increase the speed of snapshot transfer?
2. If a snapshot consists of multiple files, are the files transferred sequentially or parallely? Is there a way to make the file transfer parallel to max out available network bandwidth between nodes?
