We upgraded our infrastructure today with a faster storage device for the main system database. Until now, this database was stored on a regular (magnetic) hard disk. This hard disk was sufficient for our needs until a couple of days ago, when it started limiting the speed in which our system could handle database requests. We have therefore decided to upgrade our database to run on an SSD (a fast flash-memory-based hard disk) to help us keep up with the increasing usage of Kitely worlds.
By the way, the world nodes (the servers that run OpenSim) have been using SSDs since 2014.
