However, here are the numbers with 2.6.33.9-rt31 to compare and contrast. uname -r 2.6.33.9-rt31-00001-g76582bb sudo ./cyclictest -t32 -p 80 -n -i 10000 -l 10000 policy: fifo: loadavg: 0.10 0.31 0.15 1/543 3471 T: 0 ( 3440) P:80 I:10000 C: 5442 Min: 4 Act: 88 Avg: 138 Max: 486 T: 1 ( 3441) P:79 I:10500 C: 5183 Min: 6 Act: 70 Avg: 133 Max: 462 T: 2 ( 3442) P:78 I:11000 C: 4947 Min: 4 Act: 86 Avg: 127 Max: 399 T: 3 ( 3443) P:77 I:11500 C: 4732 Min: 5 Act: 120 Avg: 105 Max: 368 T: 4 ( 3444) P:76 I:12000 C: 4535 Min: 5 Act: 90 Avg: 126 Max: 424 T: 5 ( 3445) P:75 I:12500 C: 4354 Min: 4 Act: 89 Avg: 113 Max: 419 T: 6 ( 3446) P:74 I:13000 C: 4186 Min: 4 Act: 14 Avg: 89 Max: 428 T: 7 ( 3447) P:73 I:13500 C: 4031 Min: 3 Act: 9 Avg: 55 Max: 402 T: 8 ( 3448) P:72 I:14000 C: 3887 Min: 3 Act: 84 Avg: 65 Max: 375 T: 9 ( 3449) P:71 I:14500 C: 3753 Min: 4 Act: 68 Avg: 101 Max: 271 T:10 ( 3450) P:70 I:15000 C: 3628 Min: 3 Act: 130 Avg: 82 Max: 334 T:11 ( 3451) P:69 I:15500 C: 3511 Min: 3 Act: 110 Avg: 79 Max: 310 T:12 ( 3452) P:68 I:16000 C: 3401 Min: 3 Act: 9 Avg: 71 Max: 280 T:13 ( 3453) P:67 I:16500 C: 3298 Min: 3 Act: 7 Avg: 70 Max: 255 T:14 ( 3454) P:66 I:17000 C: 3201 Min: 5 Act: 112 Avg: 97 Max: 296 T:15 ( 3455) P:65 I:17500 C: 3110 Min: 4 Act: 69 Avg: 92 Max: 312 T:16 ( 3456) P:64 I:18000 C: 3023 Min: 4 Act: 138 Avg: 94 Max: 311 T:17 ( 3457) P:63 I:18500 C: 2942 Min: 4 Act: 86 Avg: 108 Max: 289 T:18 ( 3458) P:62 I:19000 C: 2864 Min: 3 Act: 15 Avg: 31 Max: 335 T:19 ( 3459) P:61 I:19500 C: 2791 Min: 4 Act: 71 Avg: 89 Max: 274 T:20 ( 3460) P:60 I:20000 C: 2721 Min: 4 Act: 8 Avg: 74 Max: 287 T:21 ( 3461) P:59 I:20500 C: 2655 Min: 3 Act: 68 Avg: 62 Max: 339 T:22 ( 3462) P:58 I:21000 C: 10000 Min: 3 Act: 186 Avg: 94 Max: 407 T:23 ( 3463) P:57 I:21500 C: 10000 Min: 3 Act: 93 Avg: 64 Max: 373 T:24 ( 3464) P:56 I:22000 C: 10000 Min: 4 Act: 132 Avg: 82 Max: 356 T:25 ( 3465) P:55 I:22500 C: 10000 Min: 3 Act: 133 Avg: 93 Max: 323 T:26 ( 3466) P:54 I:23000 C: 10000 Min: 3 Act: 97 Avg: 64 Max: 333 T:27 ( 3467) P:53 I:23500 C: 10000 Min: 3 Act: 134 Avg: 70 Max: 320 T:28 ( 3468) P:52 I:24000 C: 10000 Min: 3 Act: 123 Avg: 59 Max: 226 T:29 ( 3469) P:51 I:24500 C: 10000 Min: 3 Act: 143 Avg: 73 Max: 241 T:30 ( 3470) P:50 I:25000 C: 10000 Min: 3 Act: 15 Avg: 82 Max: 241 T:31 ( 3471) P:49 I:25500 C: 10000 Min: 3 Act: 10 Avg: 49 Max: 294 -- 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/
