Improving Performance
Many Unix-like operating systems and distributions are tuned for desktop or light use out of the box and not for a production database. This guide describes recommended system performance tunings for operators of new and existing Riak clusters. The tunings present in this guide should be considered as a starting point. It is important to make note of what changes are made and when in order to meas
