With these simple steps, you can significantly improve the performances of your OVH hosted WordPress.

I recommend that you benchmark your site performance before performing any changes to be able to measure the improvement.

Step1: Switch to PHP-FPM

As described in the OVH documentation, it is now possible to request your site to be handled by PHP-FPM granting better performance than the default handler.

To do so, create .ovhconfig file at the root of your site. eg.  /www/.ovhconfig

 /www/.ovhconfig

app.engine=php
app.engine.version=5.5
http.firewall=none
environment=production

Step2: Enable compression and browser caching

This is done in the .htaccess file at the root of your site. eg. /www/.htaccess

Note that I keep the SetEnv instructions as a fallback.
See more about the configuration of the .ovhconf in the official documentation (French)

/www/.htaccess

SetEnv SG_DEFAULT_PHP_VERSION 5

SetEnv PHP_VER 5_5

RewriteEngine on
## BEGIN WordPress ##

  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]

## END WordPress ##
