Real-life speed diference between 386,586 and 686 optimized distros
Distros are optimized on a wide variety of x86 architectures. It would be nice to see people's experiences about real-life speed differences between distros optimized for different hardware.
Here are the some popular binary-based distros: RedHat9 - 386, Mandrake9 - 586, Slackware9 - 386, Debian3 - 386, Vector3.2 - 686, Suse8.1 - 586 Arch0.4 - 686 Libranet2.8 - 386 I have had experience only with RH8 and MDK8.2. The speed difference between the systems was almost nonexistant..Ok perhaps MDK was a tiny bit faster... What are your observations? |
I think the major speed increases often times has nothing to do with the platform the system is running. I have used Mandrake (i586), Slackware (i386), and Gentoo (i686) boxes. Gentoo was slightly more responsive then Slackware but they were both far more responsive then Mandrake. I think the issue was with all default installs slackware and gentoo were running far less crap then mandrake. Gentoo also has the advantage of a few kernel modifications that make it better for desktop usage.
All in all GCC isn't that great at optimizing code for a particular processor but there technically should be some kind fo speed up. |
My LFS is optimized for i686, debian isn't. I don't see much performance increase on LFS, but the idea is nice :).

I dont really see that much speed increase. But I know when I compiled GNOME by hand, (i686) it was a lot more responsive than the default Slack packages.
That said, on 99% of things, I cant tell any difference. On Slack: It IS compiled for i386, but its optimized for i686 , so your losing very little "performance". And, Slackware 9 was never really i386 compliant anyway. I wouldnt worry about it. Ive tried distros of all arcs, and I cant really tell on most things. Distros(Yoper ;) ) mostly use the i686 compiling to make the distro sound faster and more up-to-date, or to easily get away from supporting old machines. |
i have gentoo 1.4, suse 8.2, and rh 9 on seperate 20g hard drs(all 7200rpm) running on the same machine. gentoo is optimized by use flags for the specific processor. openoffice apps
load faster in gentoo, browsers are a tad faster, etc. i dont know if this is really due to gentoo optimization or because i didnt install gentoo with every bit of software known to man, like i did with suse and redhat(boxed versions). the app loading speed differences are noticable but not earth shattering. oh yeah, all gnome. |
