40 000 files very very slow OC 10

I have 4 external share (cifs) for a total about 250GB and 40 000 files.
I installed OC10 yesterday on mariadb on fresh install from scratch.
I configure only apcu but it's very slow (about 1-2 files per sec) and choose cron on setting and not ajax

I'm on ubuntu 17.04.1 server up to date
I did only apt-get install mariadb-server and owncloud so I don't have any other software

Database:
mysql Ver 15.1 Distrib 10.1.22-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

PHP version:
7.0.18

ownCloud version: (see ownCloud admin page)
10.0.1

Updated from an older ownCloud or fresh install:
fresh

Where did you install ownCloud from:
repository

Login as admin user into your ownCloud and access
http://example.com/index.php/settings/integrity/failed
paste the results into https://gist.github.com/ and puth the link here.

don't understand what I have to do here sorry but iif I have to replace by my IP address so I don't have any index.php -> was not found on this server.
