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
Linux I/O scheduler queue size and MyISAM performance
At MySQL Conference and Expo 2009, I explained how Linux I/O scheduler queue size affects MyISAM insert performance. It is well known that Linux implemented four types of I/O schedulers (noop/deadline/anticipatory/cfq) in Linux kernel 2.6.10. The default is cfq in most distributions including RHEL, which is not so good then noop normally outperforms, but I'll talk this in other posts. Linux I/O sc
Your Linux AMI: Optimization and Performance (CPN302) | AWS re:Invent 2013
Your Linux AMI: Optimization and Performance (CPN302) | AWS re:Invent 2013 Your AMI is one of the core foundations for running applications and services effectively on Amazon EC2. In this session, you'll learn how to optimize your AMI, including how you can measure and diagnose system performance and tune parameters for improved CPU and network performance. We'll cover application-specific example
