1. I don't think the compile process on Gentoo is quite as big a deal as most think it is. Sure some of the bigger applications like Firefox or MythTV will take a few extra minutes to compile vs just installing. But for the smaller libraries and packages that make up the majority of a system, I find that compiling the updates from source as part of a regularly weekly update process takes up no more time than updating Ubuntu or Arch for the most part. And Portage runs quite nicely in the background. You can kick off a big update and just go about your regular work and you'll never notice anything different. You can even create a distributed compile system using spare machines on your LAN with distcc which is a lot of fun if you're into that.

- Absolute zero bloat. You have ONLY what you need. No extraneous services or bloaty apps in the background.
- (Assuming you didn't use genkernel) a kernel compiled just for your machine. That means no hundreds and hundreds of extra crap compiled into the kernel or hanging around as modules. This is probably where the largest performance gain is had.
My laptop is a Thinkpad T21 (PIII 800 Mhz, 256 MB SDRAM). Ubuntu is unbearably slow on it (partially Gnome's fault, I know). Gentoo+KDE however is nice and responsive, even with all the bells and whistles enabled short of Compiz Fusion. I will say that I'm somewhat cheating, in that with Gentoo I'm running virtually zero GTK apps. Even Firefox and its extreme memory hunger were dumped for QT based Opera. I have a theory regarding GTK based apps and their propensity to (IMHO) suck and be slow.
if you're a kde use i'd suggest you to try out building qt with qt-copy use flag and then rebuild kdelibs (search on the forums for qt-copy and you'll find out the ebuilds to do this). the amount of ram gained is about 20%. also i'd suggest thex11 overlay and from there i'd suggest the protos (except xcb that breakes the system since there was an api change with xlib and the apps aren't really patched for it) and the git mesa, cairo, glitz. the font antialiasing is really great with them. also i's suggest the live ebuild of x264 from berkano overlay and ffmpeg from flameeyes overlay. these are great multimedia ebuilds and i found out the multimedia system to be better with them installed.

Gentoo is just the very bestest thing since sliced bread Check out http://paludis.pioto.org/ while you are at it!

2. You don't have to be a developer to run Gentoo in the same way you don't have to be a mechanic to work on your car or change the oil yourself. In fact, I'm not even sure Gentoo is particularly suited to some developers/programmers. If you're writing a Java server framework or something, you may not want to fiddle with your underlying operating systems so much. So it definitely takes a special kind of user to run Gentoo. Just someone willing and interested in getting their hands dirty from time to time. Maybe likes tinkering or experimenting with a wide variety of applications. But that's the great thing about Linux. There's always something for everyone.Last edited by immudium; 02 April 2008, 12:40 PM.
