The "eseutil /k" command takes a long time to verify the checksum of transaction logs in Exchange Server 2007 Service Pack 1

On a computer that is running Microsoft Exchange Server 2007 Service Pack 1 (SP1), you use the eseutil /k command to verify the checksums of some transaction logs. However, the time that is required to verify the checksums increases as the number of transaction logs increases. For example, it may take 10 minutes to verify the checksums of 10,000 transaction logs. However, it may take 30 minutes to verify the checksums for 20,000 logs. The time to verify the checksums increases exponentially.

This issue occurs because the transaction logs are verified one at a time, and the original arithmetic for searching the next file is inefficient.

To resolve this problem, install Update Rollup 9 for Exchange 2007 Service Pack 1.
