Re: root.exe startup is slow in mac 10.6.4

Hi,

I put correct DNS and I get time measure as follows

[Mac$]time root.exe -n -l -q
real 0m3.480s
user 0m0.129s
sys 0m0.062s

[Mac$]time root.exe -n -l -q
real 0m2.132s
user 0m0.102s
sys 0m0.024s

[Mac$]time root.exe -n -l -q
real 0m32.130s
user 0m0.102s
sys 0m0.022s

First time is after fresh restart of laptop. Last one is when I remove network connections. Is there any way to solve this?

With regards,
satya
