If you have a busy PostgreSQL or MySQL database application, you might want to analyze the queries to see if they can be improved. Here's a little utility to help with that.
Last week I moderated a webinar entitled Optimizing Performance for HPC: Part 2 - Interconnect with InfiniBand. It was a great presentation with a lot of practical information and good questions. If you missed it, it will be available for a few months, so you still have a chance to check it out. As part of the webinar, Vallard Benincosa of IBM, mentioned that the speed of light was a becoming an issue in network design. In engineering terms, that is refered to as a hard limit.
collectd – The system statistics collection daemon collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD files. What does collectd do? collectd gathers statistics about the system it is running on and stores this information. Those statistics can then be used to find current performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning). Or if you just want pretty graphs of your private server and are fed up with some homegrown solution you're at the right place, too
5. Optimizing NFS Performance Getting network settings right can improve NFS performance many times over -- a tenfold increase in transfer speeds is not unheard of. The most important things to get right are the rsize and wsize mount options. Other factors listed below may affect people with particular hardware setups.
The benchmark is the SPECsfs2008 CIFS file access benchmark. There is a similar benchmark for NFS which is much more popular in terms of supplier submissions, with BlueArc, HP, Isilon, NetApp and others reporting results.
