 Posted: Fri Dec 02, 2011 5:30 am Post subject: slow system since last kernel upgrade |
 |
|
seems like my compile times take longer and longer, firefox hasn't worked since version 3 and now firefox completely freezes my system forcing me to do a hard reset every time.
I have considered the possibility that it could be the result of a hardware failure but loading my rescue cd the system just flys. without X loaded my compile times still take just as long.
dmesg output shows some ugly situations as well although I havent looked at it without x running to see what the output is.
| Code: | edit: ok let me yank out pastebin since I posted way too much info
[code]
emerge --info

and the ugly

if anything stands out to you all let me know, thanks. |

id start off by nuking the debugging bits from your kernel configuration
| Code: |
$ grep DEBUG configforum.txt |grep -v ^\#
CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC=y
CONFIG_SLUB_DEBUG=y
CONFIG_HAVE_DMA_API_DEBUG=y
CONFIG_X86_DEBUGCTLMSR=y
CONFIG_CPU_FREQ_DEBUG=y
CONFIG_PNP_DEBUG_MESSAGES=y
CONFIG_AIC79XX_DEBUG_MASK=0
CONFIG_I2C_DEBUG_CORE=y
CONFIG_I2C_DEBUG_ALGO=y
CONFIG_I2C_DEBUG_BUS=y
CONFIG_HWMON_DEBUG_CHIP=y
CONFIG_DEBUG_FS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_PREEMPT=y
CONFIG_DEBUG_BUGVERBOSE=y
CONFIG_DEBUG_MEMORY_INIT=y
CONFIG_DEBUG_STACKOVERFLOW=y
|
start with that, see if you can knock those out, see how things look after.
NB: you should also check out pappy's kernel seeds. See the links in my sig

that did produce an improvement but doing an emerge still bogs the system down dramatically. never used to.
ok dunno how that happened but i just noticed make opts was set to -j4 instead of j3. fixed that and see how it goes

well changing it to j3 has zero effect.

I think I will chalk it up to an issue with portage 2.2. if you notice your system is going nuts one emerge at a time. make sure you set EMERGE_DEFAULT_OPTS="--jobs=2 --load-average=1.5". although my emerges seem to go faster, my box is still practically unresponsive doing it.
I'm still wondering what changed so drastically with my system. and I am waiting for the text to apear on the screen as I type this because of the lag.

Greetings!
How is your free/used RAM situation when it starts 'lagging'?
Also, how is the Swap?
Seems a lot like what I was experiencing with certain builds when I had discovered half of my 4GiB RAM being bad, and going with just one 2GiB stick for a time with MAKEOPTS="-j7". 
The amount of RAM would not be enough, and things slowed down to a crawl, until the compiling got killed due to just not having enough space to work in (depending of work, of course, sometimes it might still have finish). Lowering the -j there helped a bit, and of course this is a lot different situation but I thought I'd ask, perhaps it could lead towards something.
Just a couple of thoughts~

the system only has 2 gigs of ram and almost 2 gig swap
| Code: |
Draco1 chromium # free -m
total used free shared buffers cached
Mem: 2003 1835 168 0 0 865
-/+ buffers/cache: 969 1034
Swap: 1968 670 1298
|
this is just at the start of an emerge, things are fine so far
and using top here is when it gets ugly, just trying to copy and paste this was a chore and a half.

lack of memory is an issue I seem to be dealing with on a webserver I am running, I was updating the system but emerging binutils gets to a point where the whole system just stops the emerge without error and kills my ssh connection., that box only runs 256MB.
don't worry about the server that was solved by making a larger temp swap space.
