[snip] Running this version for 2 days now on heavily used build machine. No problems to report. Here are some numbers for kernel build. Machine is SMP, 2 Xeon P4, Intel chipset, single IDE HD, with hyperthreading enabled. 2.5.67-bk4 (i think bk4): make -j1 make -j4 -------- -------- real 5m03.889 2m37.253 user 4m27.550 4m41.037 sys 0m27.727 0m29.651 2.5.70-mm1: make -j1 make -j4 -------- -------- real 4m52.212 2m41.565 user 4m27.447 4m40.462 sys 0m29.079 0m31.184 This test does not show any significant difference. On the other hand, even with -j4 the disk activity is light. If you have a better test that you would like me to run, point me to it, and I'll do it. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
