This guide describes how to tune Novell eDirectory on Linux and UNIX platforms to improve its performance, providing both eDirectory tuneables and OS specific tuneables to optimize performance when deploying eDirectory.

This method dynamically adjusts the cache limit to regulate memory consumption. A dynamically adjusting limit causes eDirectory to periodically adjust its memory consumption in response to the flow of memory consumption by other processes. You need to specify the limit as a percentage of the available physical memory.

Using this percentage, eDirectory recalculates a new memory limit at fixed intervals. While this works well in typical user scenarios, because of large differences in memory usage patterns and memory allocators on UNIX platforms, this mechanism is not recommended for optimal performance of eDirectory on UNIX platforms.
