What is the impact of 500 registers and the performance of Xstore?

We are trying to change the time interval for the data to persist in Xcenter and the replication database by changing the cycle interval to 15 seconds.

It was 30 seconds by default:

We made this change inside DtxRplicationConfig.xml

15000 is milliseconds representation of 15 seconds

<ReplicationQueue dataSource="Replication" cycleInterval="15000" maxRecsPerCycle="50" errorNotificationCycles="60">

  <relegationLevel failedAttempts="3" retryAfterCycles="30"/>

  <relegationLevel failedAttempts="10" retryAfterCycles="240"/>

  <relegationLevel failedAttempts="15" retryAfterCycles="480"/>

  <relegationLevel failedAttempts="20" retryAfterCycles="960"/>

  <relegationLevel failedAttempts="25" retryAfterCycles="2880"/>

  <relegationLevel failedAttempts="30" retryAfterCycles="9999999"/>

 </ReplicationQueue>

We have one store controller database as a whole and 300 registers in total in the organization.

How does this change impacts the performance of the application, database and system as a whole?
