Hi,
I recently renewed our web and mail platforms, and moved from horde 4 to
horde 5.
the underground services didn't change (apache, mysql, openldap, dovecot
and potfix) except for updates.
The hardware :
- two servers with High Availability : 32GB each
- and a disk array as shared storage : iSCSI with bound.
Software :
- Centos 6.7x64 (latest updates)
- Redhat Cluster Suite for HA.
- Horde 5 latest updates

High availability
we have configured two failover domains :
1 - Apache with vhost to server
- Horde portal
- our web portal, which is Liferay (tomcat7)
2 - Mail services and DB
- dovecot
- postfix
- openldap
- Mysql
We installed memcached and configured horde to use it
We tried to follow the horde performance guide, but without luck so far:
- Zend opcache is installed and activated, we tried to increase some
variables.
- We installed pecl ACP, but in horde admin configuration it is not
recommended to use it, neither xcache so what to do? for now we use
filesystem as cache.
- apache does not do DNS lookups
- We took each service apart and tune it
- openldap
- mysql
- dovecot
it didn't change anything
lastly we tried squirrelmail to test the access to emails, it was very fast.
by the way, our web portal (liferay) which uses the same openldap and the
same mysql services works perfectly.
the TOP command does not show anything strange, the two servers are
