Re: Speed? And a (good) suggestion for themes

The applications are slow to load because you enabled anti aliasing. Current releases of Xfree do not cache anti aliased font information and it has to be re-processed each time you start an anti aliased application, hence the slowness.
Wait for XFree 4.1 or turn off anti aliasing.
On my system (p2 400, 256Mb Ram), XFree 4.03 + kde 2.2 alpha 1 with all eye candy turned on, I have to wait 45s between the moment I type startx and the moment the desktop becomes usable :/ (only 6 seconds with blackbox) |

This is insane. I can report around the same numbers for my computer. Just a slight difference tho, my computer is a Cyrix 133mhz, 64megs of RAM. Not a speed daemon of any sort. (I've got KDE2.1.1, with all bells and whistles I couldn think of).
You should very well consider changing distros. I've been converting a few friends of mine lately from <many other RPM distros> to Debian lately ("There's a condition for me helping you out installing your linux machine again...") and the typical comment I get is: "Man, this runs faster, what'd you do??". I don't know what's wrong with all those distributions, but <quote>there's something rotten in the state of Denmark, and its not the cheese in the cafeteria</quote>.
In one case, the guy swears its TWICE as fast. (And no, that doens't mean the 'old' distros had millions of daemons running in the background, or such obvious performance killers)
I'm investigating the issue right now, if anyone has seen this too, please contact me.
Yours Truly,

Speed of Debian
by Ben Hall on Friday 01/Jun/2001, @11:35

Yeah, I noticed this too.
I was a long time Mandrake user before I tried out Potato and I haven't looked back.
I have two hard drives right now: Debian Sid (My main machine) and Mandrake 8.0 (for testing things like KDE alphas..) and the speed difference between the two is amazing!
I use Mandrake for an hour or two, go back to Debian and can't believe it's the same base OS and _identicle_ hardware.
It's too bad too, as all of Mandrake's bells and whistles are tempting. On the other hand, how often do you play with NIC/printer settings once they're working?
I've been working on the same Debian install from last October, Mandrake's been through several versions since then.
Debian is super-sweet. I love that I do apt-get update && apt-get upgrade and voila! up-to-date OS.
Getting back to the point, I also have no idea why Mandrake/Red Hat is so much slower. I run Apache, sendmail, VMWare, SSHd, OpenLDAP and a slew of other servers on my Debian box too, and it's zippy. I'd love to help you investigate these differences..

One of the best speed improvements you can get is by making your hard disks use DMA transfers. This will generally making things load faster.
Run hdparm /dev/hda to see what things are currently set as.
hdparm -d1 /dev/hda turns DMA on on hda.
It does make a substational difference. I think the speed difference between distros can be explained by different ones enabling it by default.

Sorry to disappoint you, but DMA was turned off on my system... (Why not? No clue...)
(Thanx for the tip tho =)
Are there any counter-advices to using DMA on HDs?

I think it is safe to use DMA, except on afew dodgy drivers/controllers.
Just thought of another speed up (well not so much a speed up, as a way to increase responsiveness which I think Debian uses) is to run X at a -20 priority instead of 0.

Be careful with hdparm and DMA. I destroyed my hard drive with it awhile back. No more hdparm for me! Back everything up first, or do it from a fresh install (where you don't have much to lose).

The difference could be in the way distros partition and use the harddisk. Harddisks rotate at a constant speed, but have more data on the outer sectors than on the inner sectors.
That means, your first partition will have a higher transfer rate than the last one.
Spliting your harddrive in several partitions can make your linux system slow if you put them in the wrong order. Beginners should only use two partitions: hda1 for swap and hda2 for /.
...and you should always have swap before your system partition to make it fast and reduce head movements.
... and Linux sometimes seems slower than Windows because Windows is always in /dev/hda1 ;-(
