I found that every time I ran "emerge --info", it will be at least three seconds for me to see the output? Also, "emerge --pretend something" will take a long time to calculate the dependencies. Is that OK?
I just want to be sure that my Gentoo box is operating normally.

Yep, normal. | Code: | ~ # time emerge --info >/dev/null
real 0m5.027s
user 0m1.576s
sys 0m0.148s
~ # time emerge --info >/dev/null
real 0m1.703s
user 0m1.556s
sys 0m0.096s |
With a cold cache, the Python interpreter has to be loaded from disk, which takes some time. For actually emerging something, then emerge is doing a dependency analysis of the Portage tree and installed packages; these databases are also not small, which is what takes the time.
