+Reducing system load
+--------------------
+
+High system load will slow down Nextcloud and might also lead to other unwanted
+side effects. To reduce load you should first identify the source of the problem.
+Tools such as htop, iotop or `glances `_
+will help to identify the process or the drive that slows down your system. First
+you should make sure that you installed/assigned enough RAM. Swap usage should be
+prevented by all means. If you run your database inside a VM, you should not
+store it inside a VM image file. Better put it on a dedicated block device to
+reduce latency due to multiple abstraction layers.

HTTP2 has `huge speed improvements `_ over HTTP with multiple request. Most `browsers already support HTTP2 over SSL (HTTPS) `_. So refer to your server manual for guides on how to use HTTP2.
+Tune PHP-FPM
+------------
+
+If you are using a default installation of php-fpm you might have noticed
+excessive load times on the web interface or even sync issues. This is due
+to the fact that each simultaneous request of an element is handled by a
+separate PHP-FPM process. So even on a small installation you should allow
+more processes to run. For example on a machine with 4GB of RAM and 1GB of
+MySQL cache following values in your ``www.conf`` file should work:
+
+.. code:: ini
+
+ pm = dynamic
+ pm.max_children = 120
+ pm.start_servers = 12
+ pm.min_spare_servers = 6
+ pm.max_spare_servers = 18
+
+Depending on your current PHP version you should find this file e.g. under ``/etc/php/7.2/fpm/pool.d/www.conf``
