[horde] Heavy load on server when using categories

[Jan Kuipers]

I noticed when using categories the load on the server increases very much. At
the moment there are only about 750 entries in horde_categories. The loadtime of
an application using categories increases with approximately a factor 4 to 5.
Particular with kronolith this becomes inconvenient (12 sec.) The server is a
500 MHz pentium III with 512 MB of memory. Does anyone else notice this?
