 |
|
Is it just me, or is the new 2.6.8 kernel waaaay slower than 2.6.7?
If I'm emerging something, xmms skips all over the place, and I know this shouldn't/didn't happen on my p4 2.0ghz computer. =\
Is anyone else noticing a lag in the new kenrel?

not here, using 2.6.8-nitro1; in fact this one is one of the most responsive kernels i have used so far

despite other problems with 2.6.8 (cdrecord, vfat, but those are different issues), gentoo-dev-sources-2.6.8-r1 is way _more_ responsive than 2.6.7-r14 imho. i think you should check your sound setup. are you using a sound server (such as esd or arts)? if so, try disabling it and use alsa as sound drivers as well as trying xmms output to be either alsa or oss.

If it was just XMMS, I'd say yeah, but if emerge is 'unpacking source', everything bogs down, even the keyboard/mouse. It also was lagging when I was copying over my backed up files from the Windows computer down the hall.
What could be causing such a situation?

intense hard disk/ide-controller/cpu usage comes to my mind, and unless you have atleast 1 Ghz cpu or even more or a raid hdd it makes perfect sense (especially when unpacking large files)

make sure your drives are using dma:
| Code: | root@mee ~ # hdparm -d /dev/hda
/dev/hda:
using_dma = 1 (on) |

I see that dma is turned off. Here's what happens when I try to enable it...
| Code: | # hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
DIO_SET_DMA failed: Operaion not permitted
using_dma = 0 (off) |
bah. How do I get this thang up and running?
