There’s always complains left and right about SocialEngine 4 being slow but the truth is you may have just have to turn Production Mode on. Go to the admin panel of your SE4 install, on the home page look at the lower right panel and you will see “System Mode” and underneath them you’ll have two buttons (Development and Production Mode). Click on Production Mode to speed up the performance of your SE4 site.
In addition to that, go to Settings > Performance and Caching to improve the performance further. You will see options under Caching Feature where the default is based on File-based which uses disk space for caching. You can choose either memcache or APC as they have a better performance over a file-based caching system.
Arvixe’s webhosting is optimized for SocialEngine4 and is highly recommended by Webligo as a webhost for your SocialEngine website.
