It is possible to connect to a kolab 16 server through the ActiveSync protocol. This makes it possible to use the Microsoft Outlook client in the most effective way towards Kolab. Kolab-syncroton, the kolab ActiveSync implementation, is installed together with the default installation.
This article outlines a two-step procedure to prevent the Kolab web client (and associated web- and HTTP-based applications) from loading the SQL database with copies of messages cached, which can potentially incur a significant performance penalty.
Memcache is a protocol to access a simple key-value store, that is memory-backed, over a network socket. The memcached server does not perform any form of access control and is optimal for certain caches used in the Kolab web client (and associated HTTP-based access interfaces), by avoiding superfluous login, access control, and other such software policy considerations, as well as disk I/O.
This article outlines the installation and configuration of a single memcached server for use with the Roundcube web client for Kolab.
The performance of Kolab Groupware web interfaces can be increased significantly by using the Alternative PHP Cache (APC user cache) and OPcache.
This article outlines the installation and configuration of both caches.
