I did a spot check of the server-recorded times for the initial 
PROPFINDs of the OSAF office calendar and one of your collections, 
Andre.  This was checked on the 8th (before update) and today (after 
update).  The initial PROPFIND during a DAV-based sync operation 
dominates the synchronization time.

Initial impressions are that there's pretty wide variance in sync times 
(from about 2 seconds to 11 seconds for the office calendar).  It 
*might* be higher after the update, if I squint, but now I want to write 
a quick statistical analysis to put some numbers behind the question.

If by "extremely long durations", you're implying 2x or more slowly than 
previously, the server-recorded numbers don't show anything like that. 
It's certainly possible you're seeing network effects, but that's 
notoriously difficult to establish.

I'd like to hear any other observations about sync times.  I sync in the 
background, so I never would have noticed if the time have actually gone 
up.  There's other operations than just the initial PROPFIND reported 
above, so there could be additional effects I haven't looked at.

Thanks for the report, Andre.  I'll be heightened to the possibility and 
take an additional look at possible causes and some real statistics.
