I have 2 openldap servers running on CentOS 5.2 (openldap-2.4.11 RPM: http://staff.osuosl.org/~jeff/openldap/el5/i386/ ), the single- master replication works fine, but when I have activated mirrormode, any ldap interaction is so slowly and CPU IOWAT is 100% (in ldapsearch or ldapadd...).

This sounds like a replication loop. Do you have serverID/rid configured correctly?

Try enabling stats,sync logs to see if that shows in the logs.
