Explain why making some replica managers read-only may improve the performance of a gossip
system.
What will be an ideal response?
First, read operations may be satisfied by local read-only replica managers, while updates are processed by just
a few other replica managers. This is an efficient arrangement if on average there are many read operations to
every write operation. Second, since read-only replicas do not accept updates, they need no vector timestamp
entries. Vector timestamp sizes are therefore reduced.
