<!-- Describe what has changed in this PR -->

<!-- Tell your future self why have you made these changes -->
**Why?**
GenerateReplicationTasks and VerifyReplicationTasks runs in parallel.
VerifyReplicationTasks runs every 2s. Verification is not instantaneous,
which means for every batch, Verification can delay at least 5s.
Increase batch size, reduce the ration of the delay in batch processing.
Before the change, RPS for GenerateReplicationTasks +
VerifyReplicationTasks is 30 RPS. With the change RPS is 90.
