The above was in reference to what version of *OpenGrouwpare* you have
and the availability of the Tasks folder.

Yep, lots of round trips makes things slower.  But it shouldn't be too
bad.  For example: I can request an event from the server and it takes
about 1/10th of a second.  Thus you can request 600 appointments in a
minute.

$time curl -u adam:* http://.../zidestore/dav/adam/Calendar/11081036
...
real    0m0.113s
user    0m0.004s
sys     0m0.008s

Almost anything WebDAV can be tested with curl,  it is a very good way
to check if the slowdown is your client/assembly or the serve. See

There is a dirty trick to request multiple objects at a time.  You can
use multiple object ids separated by an underscore to request up to 64
objects at a time.  See

CalDAV is WebDAV with extra trappings (more or less).

There have been a couple of reports that Apache's "KeepAliveTimeout"
making things slow way down.  Ideally one should set nokeepalive for
WebDAV clients.

Example: BrowserMatch "BionicMessage\.net GroupDAV" nokeepalive

So, if you use JGroupdav your performance is better?  You can enable a
trace of the back-n-forth between the client and the server;  this is
described in WMOGAG.  This might point one what differences there are
between the various WebDAV client libraries.

Are you managing files as in documents or managing contacts/etc... via
WebDAV (GroupDAV)?
