Tuning the System

Set your kernel parameters as follows:
• Make sure the
maxdsize
cachesize * entrysize + 4096
That is, if your Directory Server
average directory entry size is 20 KB, then make sure your
parameter is at least (1000*20000) + 4096, or at least 21 MB.
• Set
max_thread_proc
• Set (max number of pending timeouts) to
ncallout
• Set to at least 120.
maxfiles
utility, see Chapter 7, "Troubleshooting."
kernel parameter is at least equal to:
is 1000 (this is the default) and your
cachesize
(max number of threads per process) to 128.
