Article ID: EXAR0001 Slow Compliance Archiver throughput when Service Account Mailbox and Journal Mailobx hosted on different Exchange Servers.
In Multi-site Exchange Environment, Compliance Archiver exhibits slow throughput.
Compliance Archiver processes messages for archiving from the Journal mailbox through the Exchange Service Account mailbox used by Compliance Archiver. Performance may be degraded when the the Journal mailbox and the Exchance Service account mailbox are located on different Exchange Servers. This will cause unnecessary network traffic between the Exchange Servers.
The journal mailbox and the mailbox used by the Exchange Service Account used by Compliance Archiver should be located on the same Exchange Server host.
