Hello List,
I am running some  search performance tests , basic ldapsearch augument "cn" , on  local ldap host with rsearch, and
seeing  readwaiters:  values chainng , here is a sample from dbmon

This is not from dbmon.  This is from cn=monitor:

currentconnections: 41
totalconnections: 6407
currentconnectionsatmaxthreads: 0
maxthreadsperconnhits: 0
dtablesize: 8192
readwaiters: 9

backendmonitordn: cn=monitor,cn=userRoot,cn=ldbm database,cn=plugins,cn=config
backendmonitordn: cn=monitor,cn=NetscapeRoot,cn=ldbm database,cn=plugins,cn=co

I read the documentation for dbmon output but still need to understand what can generate this  process to wait (  the search ldap is runn locally on host), I there anything can be tune in ldap cfg  to
have this redwaiters number close to null ?
 LDAP  version:


readwaiters is the number of connections that are reading a client operation, as opposed to connections that are open but idle.

There isn't any tuning specifically for readwaiters.  Why do you think you need to do something about it?
