Performance Tuning for Content Manager

Chapter 6. Best practices for Content Manager system performance 145

After initial installation, implementing routine maintenance and monitoring can

start the performance tuning process again. This practice can help to ensure that

your Content Manager system is always being tuned for performance to ensure

that the user community is not affected by performance problems.
