It looks like google is expecting every site to use ssl in near future and I don't know what impact this has on multisite performance etc.
Starting a new multisite project I have setup on a server with plesk 12.5 using apache-Nginx. I have the free certificates from Lets Encrypt. I have a test bed using "domain mapping plugin" that has multiple domains.tld each having their own Lets Encrypt certificate.
1. Do I need a "user timeout" plugin to conserve resources ?
2. Are there any specific server and / or plugin settings for using ssl for performance?
3. Are there any problems with wpmudev plugins for multisite with multiple domains using multiple ssl certificates?
4. Are there nginx directives for this configuration?
