Build Stuff'14

The Lightning Memory-Mapped Database was introduced at LDAPCon 2011 and has been enjoying tremendous success in the intervening time. The success of LMDB has led down many different paths:

Use of LMDB eliminated bottlenecks at the database level but revealed the presence of other bottlenecks in the slapd code. Recently a number of these other bottlenecks have also been removed, yielding even greater performance gains.
LMDB has proved to be a superior database engine for many other projects and uses, and its adoption outside the OpenLDAP Project continues to grow.

The talk will cover highlights of the LMDB design, and will discuss some of the internal improvements in slapd due to LMDB, as well as the impact of LMDB on other projects.
