4. www.epd.ir EPD Co. Ltd. Linux kernel components operated consistently and completed all the expected durations of runs with zero critical system failures. Linux system performance was not degraded during the long duration of the run, the Linux kernel properly scaled to use hardware resources (CPU, memory, disk) on SMP systems. the Linux system handled continuous full CPU load (over 99%) and high memory stress well, and the Linux system handled overloaded circumstances correctly. IBM declared that these tests demonstrate that the Linux kernel components are reliable and stable... and can provide a robust, enterprise-level environment for customers over long periods of time..
