...the peripherals is *a lot* worse. Even if you set up the board for benchmarks (fix the scheduler, put everything up to 11), the quality of the external hardware (USB, SD, eMMC, etc) and their drivers do a lot of damage to any meaningful number you may extract if the moon is full and Jupiter is in Sagittarius.

After applying 125205-07 on two X4500 machines running Sol10U4 and removing "set sata:sata_func_enable = 0x5" from /etc/system to re-enable NCQ, I am again observing drive disconnect error messages. This in spite of the patch description which claims multiple fixes in this area: 6587133 repeated DMA command timeouts and device resets on x4500 6538627 x4500 message logs contain multiple

Dear all, Following the Benchmarking BOF from 2013 US dev meeting, I’d like to propose some improvements to the LNT performance tracking software. The most significant issue with current implementation is that the report is filled with extremely noisy values. Hence it is hard to notice performance improvements or regressions. After investigation of LNT and the LLVM test suite, I propose
