libmemcache-dev binary package in Ubuntu Xenial amd64

 memcached optimizes specific high-load serving applications that are designed
 to take advantage of its versatile no-locking memory access system. Clients
 are available in several different programming languages, to suit the needs
 of the specific application. Traditionally this has been used in mod_perl
 apps to avoid storing large chunks of data in Apache memory, and to share
 this burden across several machines.
 .
 Danga Interactive developed memcached to enhance the speed of
 LiveJournal.com, a site which was already doing 20 million+ dynamic page
 views per day for 1 million users with a bunch of webservers and a bunch of
 database servers. memcached dropped the database load to almost nothing,
 yielding faster page load times for users, better resource utilization, and
 faster access to the databases on a memcache miss.
 .
 This package contains the C development headers for libmemcache.
