Hello,
I am synching contacts from opencrx to Outlook with CalDavSynchronizer.
A lot of my contacts have added a picture to the vcf.
Now the Problem is that the CalDavSynchronizer thakes a very long time to sync contacts with pictures.
Without picture (from Logfile): Duration of 'CardDavRepository.Get (1 entitie(s))': 00:00:00.0530099
With picture (from Logfile): Duration of 'CardDavRepository.Get (1 entitie(s))': 00:01:24.2955027
Synching contacts with a piture to a Android or iPhone is not realy slower than a contact without a picture.
Please correct this to make the sync with photos in the VCF faster!
Best Regards,
Christian

No change after Update to CaldavSynchronizer Version 4.0.0

Please post an example vcard which causes this. 84 secs for one vcard with picture sounds strange? maybe some networking/proxy issue or timeout on the server side, if it is only when downloading the vcard. Does it only happen in the sync direction from server to outlook?
@zeiseiwogn commented on GitHub (Dec 1, 2020):
Hello, in the attachment you find a example for a contact with picture how we are using.
I dont think there is any problem with our network (no proxy using) or timeout on the server side.
Our server only supporting reading over caldav, so i dont cant testing the other way.
Feel free to contact me when you a needs more information to resolve this issue.

And what is also strange that the CPU goes to 100% on the Client with Outlook.
Duration of 'Running synchronization profile 'Test_Profile'': 07:05:34.8639785
For synching 184 contacts, and not every contact has a profile picture.
For synching the same 184 contacts to a Samsung XCover 3 it takes about 9 minutes.

Hi! Your vcf file is pretty huge, even the transmission of a 3MB picture (including the necessarybase64 encoding) can easily take the 1,5 seconds you mentioned on an average internet connection.
Could you try to resize the image to a sensible resolution (e.g. 500x500) and try again?
@zeiseiwogn commented on GitHub (Feb 23, 2021):
Hello, I am not shure what are you meaning with 1,5 second?
When you are mean the first Post "Duration of 'CardDavRepository.Get (1 entitie(s))': 00:01:24.2955027" it takes 1,5 minutes (not seconds) for one contact.
1,5 second per contact would be fine for me and not a problem!
I am synching only in local Network over 1GBit networkinterface to the server.
When it is realy necessary to try it i can, but it is not simple for me in our production system to test it.
But i know, each smaler the picture is, much faster is the snyc.
@xelan commented on GitHub (Feb 24, 2021):
Thanks for your answer. Oh, i misread the duration 😅 Sure, more than a minute is slow especially if the network is definitely not the issue. However, I think also 9 minutes (on your smartphone) is quite a long time for not even 200 contacts.
Could you try to batch-resize your contact images (e.g. with XnView) and see how the performance is with lower-res images?
@nertsch commented on GitHub (Feb 24, 2021):
Hi,
This is not a network issue.
The Vcard library, which we are using seems to have serious performance issues, when reading (deserialising) such a large vcf-File. On my machine it took 106 seconds to sync this contact from a file folder (no network involved).
I will investigate it in the next days to fix this issue.

Hi Gerhard,
thanks for your answer. When i can do anything for you please feel free to contact me.
@xelan: I am working on it to resize the pictures anyway on our contacts
Best Regards
Christian
@nertsch commented on GitHub (Feb 27, 2021):
It it fixed and takes now a few milliseconds to deserialize such a big contact.
The fix will be included in the next release.
