Very long time display of the contact list

[ionl]

Steps to reproduce

1. Only click on the contacts app

Expected behaviour

1. Quick request :-)

Actual behaviour

1. I tested a lot of time and it takes about 17s to 19s to show contacts list. I have about 500 contacts. I set APCu data cache. I have only 1 picture.

Server configuration

• Contacts app version: 1.5.3
• Nextcloud version: 11.0.3

• Database and version: MariaDB 10.0.30
• Server Distribution and version: debian 8 kernel 3.14

Client configuration

• Distribution and version: ubuntu 17.04 kernel 4.10
• Bandwidth 2MB/s

I wanted to ask the same. And i think its the pictures loading that long (in my case). I watched my network traffic and it is loading many MB and takes much too long to show up the needed information.

Would it be possible to first catch only the cards without pictures and bring it up? After this loading the pics as thumbnails would speed up.

I confirm that the time required to display the contacts is related with the download of pictures. With a network connection limited to about 256 kB/s, it took 8s without pictures and 1'30s with pictures for the same 392 cards.
It would indeed be better to download the pictures after having downloaded the cards.

Performance issue, tagging as high – @nextcloud/contacts @nextcloud/javascript

Is it only related to the pictures? I have the same performance issue on mine (nextcloud 12, php7) and after enabling performance recording in Firefox, I saw that the two most time consuming calls are https://XXX/remote.php/dav/addressbooks/users/XXX/contacts/ (REPORT, it is 1.4M big) and the same as (PROPFIND). Then the downloading of angular.js?v=4a87eb2f1684b77467c938531f75b836-19 and core.js?v=4a87eb2f1684b77467c938531f75b836-19 also takes some time (these are big).

I have between 150 and 200 contacts, around half with pictures (most of the pictures must be relatively low-res).

PS: by the way, it also reports that "Content Security Policy: The page’s settings blocked the loading of a resource at self (“script-src 'nonce-c1BjUm9RMlFlM0hEL1J3a2plbm5Vejk1UG4wUk1BUnB5RGZOM2tJZ0VETT06L281bjcwTGNTUnFIbkU5WHVwMkpDV2txZWhSd0JVMGduM1dFbENVVVVsOD0=' 'unsafe-eval'”). Source: ondrop attribute on INPUT element."

I have only 1 picture on about 500 contacts and it takes about 17s to 19s to show contacts list.
My connection is very poor : 2MB/s

The new update 1.5.4 should improve things a lot.
Would you please update this post after? :)

[ionl]

Yes!
Thanks very much! :)

[EddyLB]

Will do. Thank you so much!

With over 2k contacts first contact shows after 20 seconds, after ca. 30 seconds Firefox gives a warning that "page is making browser slow", the list is finally loaded after 40 seconds.
Search is also working very slow.

It definitely needs optimization:-)

@ionl @pafcioooo @EddyLB Please take a look at the latest nightly.
https://nightly.portknox.net/contacts/nextcloud_contacts_nightly_build_2017-09-14.tar.gz

[pafcioooo]

@skjnldsv, above mentioned nightly build is a huge improvment! 👍

Full contacts list is loaded in 13 seconds! :-)
Search is working almost immediately.
Scrolling is also working smoothly.

Only after selecting a contact, its display time is too long, between 7-10 seconds. I am not sure what it depends on.

Thanks a lot anyway:-)

[skjnldsv]

@pafcioooo there was a fix for this I think.
Please take a look at the latest nightlies! :)

Glad to hear the loading improved a lot!

[pafcioooo]

@skjnldsv, ok I have also tested latest nightly build and display activities work the same as with previous build.

From time to time after selecting some contact I get "page is making browser slow" in Firefox.

[skjnldsv]

@pafcioooo This is strange, I don't have this issue.
Could you open a new one and include some network xhr requests stats (size, time), some info about your uplink speed... etc :) ?

[skjnldsv]

fixed by #88 (ref #12)

I've just installed nightly_build_2017-09-21 and on my side, the initial loading is still quite slow... around 15s when reloading the page. On the other hand, since my nextcloud is running on a raspberry pi2, it could be that the database (mysql) slows everything down... (when running a tool such as mysqltuner, it complains a lot about the database structure)
