 * Hi,
 * I´ma using my WordPress multisite for a long and have installed your great plugin
   also for several years. Since I got an own server with 8 cores, 16GB ram and 
   nginx I wonder why loading of my sites is a little bit slow till the ressources
   are found. Means: I think it lasts to much time where your plugin redirects from
   the given subdomain to the permanent redirect domain. I´ve analysed it with P3
   Plugin Profiler and nearly 50% of performance issues are related to MU Domain.
 * I don´t know why. I´am using IP adress of the server for lookup, and have configured
   the plugin only with permanent redirect. Each site has 2 domains: [http://www.xy.de](http://www.xy.de)
   and xy.de, while [http://www.xy.de](http://www.xy.de) is the primary domain.
 * At nginx I use the standard rules ([https://gist.github.com/benhartwich/983e6b190ea2b10ca094#file-multisite-sample-subdomain-conf](https://gist.github.com/benhartwich/983e6b190ea2b10ca094#file-multisite-sample-subdomain-conf),
   [https://gist.github.com/benhartwich/983e6b190ea2b10ca094#file-multisite-mu-domain-mapping-conf](https://gist.github.com/benhartwich/983e6b190ea2b10ca094#file-multisite-mu-domain-mapping-conf))
   and each domain is routed to the main folder of the wordpress multisite. I don
   ´t know, what can do the trick to get a faster redirect?
 * Any hints?
 * Best,
 * Ben

 * With that much RAM it’s possible that nearly all queries in your install are 
   being retrieved from the object cache instead of the database. The DM plugin 
   does not employ object caching in the domain lookup.

 * Thanks! If I understood you right, this would be a feature request? Or is anything
   which I can speed up?

 * Arbitrary URLs is going to be added to core WP in version 4.4. There won’t be
   any further development on this plugin.
 * If the 2 blog lookup queries that the DM plugin does represents close to 50% 
   of your performance your setup is probably as optimized as you are going to get.

 * Hi,
 * no net really. But with nginx (spdy) 1.80 and a little bit php tuning I get good
   results. Anyway we´ve to wait till this feature is a core element.
 * Best,
