A three-pronged attack on performance
A computer running Linux can outperform the same computer running Windows XP or Vista. Even so, you may be able to make your Linux system even faster. Here are three optimizations, at different levels, that can make your Linux system perform better.
As with all optimizations, you won't be able to tell whether you are really getting better results without doing some simple benchmarking. Many processes run on a normal Linux PC, and they can affect performance measurements. To minimize their impact, we will work at init 1 level -- single-user mode, in which only minimal processes run. Start a console (ALT-F1 will get you there), log in as root, and execute the init 1 command. This will shut down most services and applications, and let you get consistent results.
Even being in runlevel 1, you should then use the ps xaf command to check whether there's something running that shouldn't be; in my case, I discovered that the ddclient program was running (actually sleeping) and might have changed my results, so I ran kill ddclient to get rid of it.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
