First time the DB was built it took more than 13 hours to complete. Not exactly sure how much, i left the computer on to complete this while going home from work. From home I checked once and saw that it was still running. Then it was almost 13 hours after starting. > > Sorry for that... no problem. we are here for this only, :) And this is only for the first time. Next time I again ran build_kernel_data.sh , it was something around 1.5 - 2 hours. Now test_kernel.sh is running on another terminal, lets see how much time it takes. >What kind of a computer are you using? RAM and > number of cores? Do you have hyperthreading? 64bit, 4 core, 8GB ram, CPU MHz: 3000.000 hyperthreading not there. Just one thing, your test_kernel.sh was taking NR_CPU as 4, I hardcoded that to 8.

I will try to give you this stat by monday. regards sudip -- To unsubscribe from this list: send the line "unsubscribe smatch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
