This makes a significant difference when loading large files and during commit and clear operations, thanks to improved cache locality. In the measurements below, master refers to the code before any of the changes to the patterns code, not the code before this one commit.

HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
