theory: binary vs. source

[Timo --Blazko-- Boewing <blazko@online.de>]

Hi again,

i got a somewhat theoretical question: in /etc/apt/sources.list there is
a destinction between deb abd deb-src packages. Are the deb-src packs
"make'able" packages?

*** core question *** :^)
But the question of interest: on nowadays PCs - assuming a "every user"
system with e.g. X-Window w/ GNOME etc. - may there be a noticeable
performance (e.g. > 5%-20%) between i386 binaries or optimized
self-comiled apps?
*** /core question *** :^)

While using apt-get/dpkg only, in the past i nearly always used tarballs
with app sources, but compiling made me crazy due to unmatched
dependncies and sometimes broken packages.
Anyhow, i am still addicted to do self-compiling.

Btw.: assuming i only would use deb-src, will it get the source archives
including all dependencies so that i can comfortably compile all the
stuff myself?

Hope for a discussion (will see it tomorrow, time to sleep *g).

Thanx in advance & greetings,

Timo
