If you are experiencing an error running the userbench suite of tests, and the error indicates “ERROR: Sphere GPU benchmark failed, aborting further tests on this GPU” then this MAY solve your issue. I isolated this error on my system to the Nahimic service that is a part of the Realtek Audio driver package. To… Continue reading Userbench fails Sphere graphics test. Possible solution.

Sometimes it’s nice to disable EXT4’s journaling.
I find that when I run F19 natively on a USB drive, disabling the journaling of the EXT4 filesystem improves performance significantly. tune2fs -O ^has_journal /dev/sdf1
Latest benchmarks for i5 2500K
I just completed a new workstation using an Intel i5 2500K processor, with a Asus P8Z68-V Pro motherboard. The benchmark that follows compares the performance differences between Fedora 15 and Kubuntu 11.04 using the exact same system. Kubuntu 11.04 vs Fedora 15 benchmarks
Fedora 13 benchmarks.
I have created some new Fedora 13 benchmarks. I have published the results on Phoronix I am particularly proud of the 12,500 inserts into SQLite in 17.11 seconds..

Tom’s Hardware benchmark confirms i5 660, i5 661, i7 870 faster than i7 980x.
This benchmark was for Lame and the results indicate that the i5 660, i5 661, and the i7 870 all tied for first when encoding audio from wav format to mp3 format. They all outperformed the i7 980x. Lame is obviously not SMP for more than 2 cores. I said something to this effect back… Continue reading Tom’s Hardware benchmark confirms i5 660, i5 661, i7 870 faster than i7 980x.
VelociRaptor 10,000 RPM 600G hard drive released!
Today I received the Official Western Digital announcement for the new VelociRaptor 10,000 RPM 600G SATA 6G/s drive. Sounds impressive. If we were limited to mechanical drives, this one definitely would be the one to have for performance. The problem is, we are not limited to mechanical drives. Solid state drives are readily available. The… Continue reading VelociRaptor 10,000 RPM 600G hard drive released!
Phoronix Global benchmark Top of the World. Why yes, Virginia, that is a 16 Core Dell R900 that I just out performed by Thirty-Three PERCENT, with a dual core system that was not overclocked.
My criterion for valid benchmarks.
Recently I have fielded many inquiries related to building the fastest servers available. So, in reply. I am publishing the list of criterion I adhere to. These are requirements for the server systems that I build and sell for production web or file servers. My standards of quality and moral values in this regard will… Continue reading My criterion for valid benchmarks.
