Switch the Ruby memory allocator from Glibc malloc to Jemalloc. Jemalloc supposedly uses less memory than Glibc malloc because it's better at handling memory fragmentation. It also has detailed internal statistics to help monitor allocator behavior. We use the LD_PRELOAD method of loading Jemalloc instead of building it into Ruby so that we can switch allocators at runtime.
Config
This directory contains configuration files for Danbooru.
To configure your Danbooru instance, copy danbooru_default_config.rb to danbooru_local_config.rb and edit it. See danbooru_default_config.rb for details.
The only file here that end users need to be concerned about is danbooru_default_config.rb. The rest of the files here are internal Rails-related configuration files that end users shouldn't need to edit.
