I have re-run my benchmark because i wasn't happy with what i had told you.. i had taken the 40% improvement from an early benchmark i did at low speed. so, i have executed the benchmark at 918Mhz instead. For reference, the benchmark is: sysbench --test=cpu --max-requests=50000 --num-threads=4 --max-time=15 run I don't know how good/bad this is as a benchmark.. but it seemed ok for my 2-cent benchmarking. The benchmark report min/avg/max time it took to process 1 request during the test run. At 918Mhz, using the vendor 3.4 kernel, i am seeing (in ms): 25.02/26.05/31.89 And with our current 'mainline' kernel, i am getting: 25.14/58.72/121.67 and it's quite consistent over multiple runs. So it's much more than 40% actually.. if we apply these ratios we get theoretical numbers that makes more sense... the ifc6410 should definitely be faster than panda.. cheers nico _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
