If you want a faster Kolab, read this.

[Rangel, Rolando]

I got Kolab 3.4 on Debian 7.8 working with several accounts/devices 
running on a 1GB linode virtual server with SSD drives and Varnish. It's 
super fast. My address book has more than 4k names, emails and phones 
that are updated instantly. Email, tasks, notes, calendar, tasks are 
super fast also.
