  • Rediscovering sar

    Posted July 22, 2012 - 7:00 pm

    The best trick for understanding performance problems on a Unix system is to understand performance when it ISN'T a problem. If you know what acceptable performance looks like, you'll quickly spot what's out of whack when a system is hurting. And one of the best tools for routine performance monitoring is built into many Unix systems -- sar, the system activity reporter.
  • How to benchmark your PC for free

    Posted July 7, 2012 - 7:09 am

    Running benchmarks on a PC enables users to evaluate performance, to identify potential bottlenecks, and to choose effective system upgrades. Unfortunately, many users imagine that system performance is simply a matter of CPU frequency or memory capacity, which leads them to think that dropping in a faster CPU or more memory will automatically and immediately yield noticeable performance improvements. In reality, however, that is not always the case.
