For the best performance, configure the host server before configuring the Directory Server instance by running the setup-ds-admin.plscript.

2.2.2.1. Perl Prerequisites

For Red Hat Enterprise Linux systems, use the Perl version that is installed with the operating system in /usr/bin/perl for both 32-bit and 64-bit versions of Red Hat Directory Server.

2.2.2.2. File Descriptors

Editing the number of file descriptors on the Linux system can help Directory Server access files more efficiently. Editing the maximum number of file descriptors the kernel can allocate can also improve file access speeds.

1.First, check the current limit for file descriptors:

cat /proc/sys/fs/file-max

2.If the setting is lower than 64000, edit the /etc/sysctl.conf file, and reset the fs.file-maxparameter:

fs.file-max = 64000

3.Then increase the maximum number of open files on the system by editing the
