They're pretty straight forward to do; see: > > http://interbench.kolivas.org I couldn't take down any lower power machine for these benchmarks... A lower power single cpu machine would be better for this. Feel free to throw any other benchmarks at it. This core2 duo 2.4 GHz with 2GB ram and 7200 rpm 16MB cache hard drive is not too discrimanatory, but here are the results (use fixed font to see): Using 2392573 loops per ms, running every load for 30 seconds Benchmarking kernel 2.6.20 at datestamp 200702181608 --- Benchmarking simulated cpu of Audio in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met None 0.002 +/- 0.00329 0.006 100 100 Video 0.002 +/- 0.00356 0.01 100 100 X 0.007 +/- 0.0819 2 100 100 Burn 0.002 +/- 0.00335 0.005 100 100 Write 0.105 +/- 1.55 35.5 100 100 Read 0.006 +/- 0.00707 0.014 100 100 Compile 0.312 +/- 5.61 135 99.8 99.8 Memload 0.01 +/- 0.037 0.72 100 100 --- Benchmarking simulated cpu of Video in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met None 0.004 +/- 0.00431 0.017 100 100 X 0.006 +/- 0.00608 0.013 100 100 Burn 0.003 +/- 0.00392 0.012 100 100 Write 0.097 +/- 3.44 144 99.8 99.8 Read 0.005 +/- 0.00523 0.013 100 100 Compile 0.059 +/- 1.2 36.7 99.8 99.8 Memload 0.01 +/- 0.0767 1.85 100 100 --- Benchmarking simulated cpu of X in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met None 0.056 +/- 0.379 3 98.4 96.7 Video 0.033 +/- 0.258 2 98.7 97.7 Burn 0 +/- 0 0 100 100 Write 0.051 +/- 0.67 11.2 99.3 99 Read 0.053 +/- 0.384 3 98 96.7 Compile 0.139 +/- 2.29 39 99 98.6 Memload 0.166 +/- 2.25 39 98.1 97.1 --- Benchmarking simulated cpu of Gaming in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU None 0.551 +/- 0.553 0.665 99.5 Video 0.594 +/- 0.596 0.656 99.4 X 0.019 +/- 0.317 5.49 100 Burn 179 +/- 186 193 35.9 Write 1.16 +/- 5.87 69.2 98.9 Read 0.876 +/- 0.884 1.31 99.1 Compile 193 +/- 209 499 34.1 Memload 1.11 +/- 1.59 15.3 98.9 Using 2392573 loops per ms, running every load for 30 seconds Benchmarking kernel 2.6.20-ck1 at datestamp 200702181542 --- Benchmarking simulated cpu of Audio in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met None 0.002 +/- 0.00333 0.005 100 100 Video 0.004 +/- 0.0309 0.717 100 100 X 0.008 +/- 0.124 2.99 100 100 Burn 0.002 +/- 0.00339 0.005 100 100 Write 0.03 +/- 0.228 2.99 100 100 Read 0.005 +/- 0.00636 0.017 100 100 Compile 0.041 +/- 0.268 3.06 100 100 Memload 0.31 +/- 4.83 6.3 100 100 --- Benchmarking simulated cpu of Video in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met None 0.003 +/- 0.00383 0.014 100 100 X 0.008 +/- 0.143 5.99 100 100 Burn 0.003 +/- 0.00383 0.009 100 100 Write 0.023 +/- 0.219 4.57 100 100 Read 0.004 +/- 0.0047 0.017 100 100 Compile 0.027 +/- 0.214 3.73 100 100 Memload 0.015 +/- 0.113 3 100 100 --- Benchmarking simulated cpu of X in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU % Deadlines Met None 0 +/- 0.000351 0.006 100 100 Video 0 +/- 0 0 100 100 Burn 0 +/- 0.000293 0.005 100 100 Write 0 +/- 5.85e-05 0.001 100 100 Read 0.003 +/- 0.0585 1 100 99.7 Compile 0.15 +/- 1.09 14 97.3 95.6 Memload 0 +/- 0.00105 0.018 100 100 --- Benchmarking simulated cpu of Gaming in the presence of simulated --- Load Latency +/- SD (ms) Max Latency % Desired CPU None 0 +/- 0 0 100 Video 0.006 +/- 0.115 1.99 100 X 0 +/- 0.00283 0.049 100 Burn 187 +/- 225 270 34.8 Write 1.38 +/- 6.8 99.4 98.6 Read 0 +/- 0 0 100 Compile 205 +/- 246 440 32.8 Memload 0.005 +/- 0.0295 0.282 100 -- -ck - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
