Not sure if this is the correct forum, but it is on a laptop, so here goes.

I seem to be getting hellishly bad performance. KDE runs slower on this machine, which is specced below, than it does on my other laptop (Which runs Mandrake 9.0).

Current Gentoo laptop specs:

2.4Ghz Pentium4
512meg of DDR RAM
40 gig drive (20 gig NTFS WinXP partition, rest split for Gentoo)
8x8x8x24x DVD/CD-RW drive
Radeon Mobility 9000 (64meg dedicated DDR, AGP4x)
2xPCMCIA slots
4xUSB2.0
1xFirewire
IR port,
Sony Memory stick card reader (Yes, inbuilt)
Some other blurb I ignored...

Older Mandrake 9.0 Laptop:

1Ghz Celeron
256meg of SD-RAM
20gig drive (10 gig WinXP NTFS, 10 gig Linux)
4x DVD drive
S3 Savage4 Twister card (32 meg SHARED)
1xPCMCIA
3xUSB1.1

and that's about it

Also note I have a problem with the consoles on Gentoo with the P4... After about 5->10 minutes the keyboard will cease to work, forcing me to reboot. This doesn't happen in X however....

Generally things boot and look something like, but the system is slow and unresponsive and prone to some pretty serious stability issues.

Is it just me or is this a bad thing?

MMC/SD card reader (Yes, also built in)

Have you tried looking at your processes, and trying to see if any are maxing out your cpu or memory?

Try removing apm/acpi support and see if the performance issues go away, this is effecting quite a few people.

If this fixes it but you want acpi I think you can grab acpi-sources and use that without problems.

I have been running KDE 3.1 with no problems until this last week. I could start ANY KDE application and have enough time to go get a cup of coffee and a snack and still have to wait for the application to come up. Anything non-KDE was no problem. I have seen in the postings that fam was causing that problem and also if the hosts file was not correct.

Mine was different, in fact I just solved the problem before coming online tonight. I had been fiddling with user mode linux and had modified my firewall so that I could emulate networking communication with user mode linux. I noticed that if my firewall was not up, no problem and I only noticed the problem when not running user mode linux.

I commented out the firewall lines applying to masquerading and my problem was solved. I guess more work is needed on my firewall for this.

Yup, Average CPU usage jumps between 0 and 4% during a KDE session. Funnily enough compiling seems to fly (As you might expect on this machine)

Ain't got and APM/ACPI support. I don't think I added it to the kernel or anything.

Interesting, I'll poke that. I have a smoothwall router/firewall. And I seem to remember gnome shouting that it couldn't look up it's own host name, but I just added it to the hosts file as 127.0.0.1 So I don't really see that being the problem?
