Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

My RedHat 8.0 system is lagging like crazy, especially after I messed with my "Look and Feel" settings. My system is setup like this:
Intel Celeron 733MHz
30GB HDD (split: 15GB for Linux, 10GB for XP, ~2GB for Swap)
40x12x40 Samsung CD-RW
Dual Booting XP Pro and RH8
Running KDE on RH8
Resolution is like 1400xsomething (dont remember; the second highest option)
Kernel is 2.4.18-something
Anyone know how I can get RH8 to even come close to match the performance of XP? XP is at least ten times faster than my RH8... when I open something in RH8, it takes at least a full minute before it appears on the screen... and when I'm browsing the internet, it lags like crazy, especially when it's using Java such as on Yahoo! Pool. Oh, and by the way, which is better and why: KDE or Gnome?
Which windowmanager is better is mostly a question of taste. You may like to try a lighter desktop like IceWM or XFce, they will run faster than KDE and Gnome, although with your specs there shouldn't be a problem. Also I would suggest using Galeon for webbrowser, it's faster than Mozilla. And besides, there's probably no need for 2 gigs of swap. Someone told me a swap partition of more than 256MB will slow down the system, although you can have more than one swap partition if you really need the space.
And if you really want a more performance enhanced Linux distro, you should try Gentoo.
Something is wrong with your system. It shouldn't take that long for it to do normal activities especially with a 733MHz processor and 320M RAM. A good rule of thumb for the size of SWAP is anywhere from 1X to 2X the amount of RAM, but I don't think it should slow the system down that much.
When you notice a slowdown run the top command to see what is running. Also the ps command might be informative. Check /var/log/messages for errors. I would go back to look and feel and turn some of the settings back down. Things like animated menu effects can really hog memory. Plus your resolution is really high...1400x!
Some processes will be faster in XP, but RH should be as fast if not faster for the majority of things. You might want to be more specific as to what things are running slow.
As far as KDE vs Gnome, I think they're both great desktops and it's really a matter of your own opinion. You can be more adventurous and try one of the NextStep-ish desktops like yngwin mentioned as well, though they do take getting used to.
If you like minimal windowmanagers, I think there's nothing better than waimea, my favourite. Also fluxbox is popular. As you are running RedHat now, look for packages on your install cds, or maybe they have some ftp-site?
I'm glad I found this thread! I seem to have the same problem.
Shouldn't the performance of RH8 be at least in the ballpark with Win98? I just installed RH8 on a Compaq Armada 7710MT Laptop (Pentium 150, 144 MB ram), on a removable hard drive (the kind that is standard on this computer) of it's own.
I was shocked to find how slow things seemed to be. The boot process is not inordinately long, but once you get KDE or Gnome running, starting a program takes forever. Once programs are loaded, things don't seem too bad.
It does not appear that anything is wasting CPU cycles, as the load average is in the .1 range when the machine is idle.
Any suggestions on where I might look for the cause of this would be appreciated.
I have a Dell Inspiron 8200 with the following configuration:
1.8 GHz processor
1600x1200 LCD panel
NVIDIA GeForce 4 Go 440
I installed Red Hat 8.0 and cannot believe how incredibly SLOW this damn OS is! Mandrake and SuSE had no speed problems. I always run GKRELLM and see the CPU almost always fluctuating between 1 and 6%.
When I just ran the updatedb command, with paths pruned to the core files I'd want to search, it ran for more than 5 minutes. The GNOME System Monitor constantly showed it using 0% CPU during this time.
When I start ANY program, shell, utility, it really doesn't matter, it takes upwards of 1-2 minutes before the program loads.
Finally, when I drag a window, or other such operation, the window is constantly "behind" the cursor movement.
This is totally unlike ANYTHING I've seen before with the other versions of Linux.
One question, does hard disk DMA have to do anything with the slowdown? Maybe that is the problem, it happened to be the problem with a PII 366 Mhz laptop with 64 MB of RAM I was working on. I enabled DMA, and then the system was so much faster.
it's the driver! (and perhaps more) READ THIS if you have Armada 7700
First, thanks to all who responded! Hopefully, the following will be helpful to someone in the future!
As installed, hdparm and the drivers would not allow DMA to be enabled, although enabling 32-bit transfers (hdparm -c1 <device>)
did increase performance from approx 2.3 to 3.4 MB/s.
Examination of dmesg output revealed that there was no support present for the Compaq IDE controller. Some web searching revealed that a driver has been recently written, and is part of the 2.4.21-pre5 kernel.
Building and installing that kernel improved things to around 10.5 MB/s, but there appears to room for improvement. It appears that the drive remains in mdma2 mode, when it is capable of at least udma2.
There IS some kind of configuration problem with Red Hat 8.0 (fully patched or unpatched). I already tuned my hard drive like this:
hdaprm -a64 -A1 -c3 -d1 -k1 -K1 -m16 -r0 -S36 -u1 -W1 /dev/hda
For the DVD/CD-RW, I configured it like this:
hdparm -c3 -d1 -k1 -K1 -r0 -u1
Here's the interesting point, when I ran hdparm -t -T /dev/hda on Red Hat BEFORE X starts, the numbers look great:
timing buffer-cache reads: 343.14 MB/sec
timing buffered disk reads: 21.24 MB/sec
Now take a look after X starts on Red Hat:
timing buffer-cache reads: 346.14 MB/sec
timing buffered disk reads: 10.32MB/sec
Compare that to Mandrake Linux 9.0:
timing buffer-cache reads: 387.88 MB/sec
timing buffered disk reads: 20.71 MB/sec
And this isn't the only machine this is happening on. I've installed RH 8.0 on a Dell server, a Dell workstation, and a Dell laptop (mine). ALL have the same lousy performance characteristics. Unless a program has been loaded already and is in cache, we ALWAYS wait 15-17 seconds (at a minimum) before the program actually opens. When I opened OpenOffice writer on my laptop, the program required 1 minute and 22 seconds to load!
Good luck to those of you sticking with Red Hat. Our company has decided to move to a more responsive Linux: Mandrake.
