IBM® Sametime® administrators can make adjustments to the servers they maintain to provide optimal performance for users as they use instant messaging and web conferencing.
Complete the following tuning procedures to enhance performance.
Set verbose garbage collection logging in the IBM® Sametime® Connect Client.
If your IBM® Sametime® server is hosted on Linux™, increase the number of concurrent open files on the server to prevent performance problems.
By default, the Meeting Room Center searches the Meeting Room Center database for rooms without using an index.
