'samba_dnsupdate' should now be more reliable as it will now find the appropriate name server even when resolv.conf points to a forwarder. +Significant AD performance and replication improvements +------------------------------------------------------- + +Previously, replication of group memberships was been an incredibly expensive +process for the AD DC. This was mostly due to unnecessary CPU time being spent +parsing member linked attributes. The database now stores these linked +attributes in sorted form to perform efficient searches for existing members. +In domains with a large number of group memberships, a join can now be +completed in half the time compared with Samba 4.6. + +LDAP search performance has also improved, particularly in the unindexed search +case. Parsing and processing of security descriptors should now be more +efficient, improving replication but also overall performance. + Query record for open file or directory --------------------------------------- -- 2.34.1
