While I'll start by backing up everything said by others regarding the |
26 |
differences being nearly negligible in a truly equal test, same feature set |
27 |
from source vs the feature set provided by a binary distro, and even a loss |
28 |
in terms of total time when you include the compile times involved, I do |
29 |
have a bit of anecdotal evidence in Gentoo's favor. |

|
31 |
On the majority of x86 or x86_64 hardware there's very little room for |
32 |
across the board gains in performance over otherwise standard cflags. On |
33 |
slightly less 'normal' hardware, like, say, an Atom N270 based netbook with |
34 |
1GB of ram, however, a few cflags go a *long* way towards having a usable |
35 |
system. My Mini9 shipped with a variant of Ubuntu that's actually built |
36 |
with general optimizations to make it usable on that hardware, and having |
37 |
run the same version of Ubuntu without those optimizations for a day or two |
38 |
on it, the amount of stutter and stalling was almost unbearable. Then, with |
39 |
the help of a desktop (or three) to handle the bulk of the compilation, I |
40 |
moved to Gentoo on it. I hadn't sorted out what cflags would be best, and |
41 |
simply built what I needed to get back to work on it with fairly minimal |
42 |
use flags, and I was rather frustrated to find that it still ran worse than |
43 |
the factory install, once programs had started (though that process |
44 |
was noticeably faster, as it generally is with so much less running in the |
45 |
background). Once I adjusted to the appropriate cflags, the stutter cleared |
46 |
up, things didn't stall frequently, and the system was simply more |
47 |
responsive. I could even watch flash videos full screen without it |
48 |
stuttering, which I'd given up on as a possibility on the system. A vast |
49 |
majority of the gains I saw were simply from clearing away the 80% of |
50 |
Ubuntu's features I have no use for, but when you have a processor that |
51 |
approaches things just a little differently, like an Atom, you really can |
52 |
gain a bit from letting the compiler put things in an order the processor |
53 |
will agree with better. |
