Instant Messaging Disk Throughput

Disk throughput is the amount of data that your system can transfer from memory to disk and from disk to memory. The rate at which this data can be transferred is critical to the performance of Instant Messaging. To improve efficiency in your system’s disk throughput:

• Consider your maintenance operations, and ensure you have enough bandwidth for backup. Backups can also affect network bandwidth, particularly remote backups. Private backup networks can be a more efficient alternative.

• Carefully partition the data stores to improve throughput efficiency.

• Ensure the user base is distributed across RAID (Redundant Array of Independent Disks) environments in large deployments. Typically, you make this decision as part of the Directory Server deployment planning process.

• Stripe data across multiple disk spindles in order to speed up operations that retrieve data from disk.
