I haven't blogged in a while, but there has still been a lot of activity going on behind the scenes. We moved to a newer version of Ubuntu for our server, optimized some queries and indexes, migrated to InnoDB, trimmed some code bloat to improve performance, fixed some bugs, improved preloading to add more cases where it is used, changed Mark All Read so your previous timeframe will be remembered, and more.
Hopefully the benefit you will see from all of this work is a much more responsive experience and allow you to spend more time reading and less time waiting.
