Hi list, I am running AMD Duron 750 MHz, 128 RAM with SuSE 10.0. Normally it is on acceptable speed, but sometimes (especially when running OpenOffice before extremly important presentations) it is quite slow. So what I want is to turn off the services which I definetely do not need. As I am not much experienced to know what I definetely do not need, I ask for your help ;) First, I do not need any network(at this time) and I haven't got printer and scanner, so can I turn off from the chkconfig the following services?: cups (for the printer) mdnsd postfix sshd This is what I feel may be turned off, maybe I missed something...(I can post my chkconfig output, if you need) Besides, do I need six mingettys, can I turn them off from /etc/inittab and leave only one? Also there is so much files in my /dev, but I haven't got so many devices, does it eats resources? I just didn't wanted to make a long post, but can provide any info you need (processes, chkconfig etc.).

Hi list,
I am running AMD Duron 750 MHz, 128 RAM with SuSE 10.0. Normally it is on acceptable speed, but sometimes (especially when running OpenOffice before extremly important presentations) it is quite slow. So what I want is to turn off the services which I definetely do not need. As I am not much experienced to know what I definetely do not need, I ask for your help ;)
First, I do not need any network(at this time) and I haven't got printer and scanner, so can I turn off from the chkconfig the following services?:
cups (for the printer) mdnsd
Can be turned off.
postfix
Depends on your mail setup - can be turned off. But then you won't get root mails.
sshd
If nobody needs to access the machine remotely: Turn it off.
This is what I feel may be turned off, maybe I missed something...(I can post my chkconfig output, if you need)
Besides, do I need six mingettys, can I turn them off from /etc/inittab and leave only one?
Yes, they run on the console only, so if one is enough for you.
Also there is so much files in my /dev, but I haven't got so many devices, does it eats resources?
A little bit since /dev is on tmpfs (a ram disk). But we only create a minimal set, there's not much too delete and you need to do it at each boot.

It is probably dead busy paging and swapping. 128Mb is really on the low side, certainly when you're running Openoffice.

Yep.

Yes, you can turn them off.

Nope. I don't think any of this will make your system go much faster - for Openoffice you simply need more RAM. /Per Jessen, Zürich -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com

More ram would help you speed problem some. Ram is pretty cheap now days, you might try adding 512 megs an see if that helps also. jack -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com

Hi Sergey, I'm running a 900MHz Duron with one 512MB stick of PC133 memory and a dedicated 1GB swap partition. This system is still extremely responsive. It takes longer to load certain applications like OpenOffice, but once loaded I have no problems creating or editing files. I agree with the others that your most severe problem, a bottleneck really, is low memory. Try that first and see if your problems disappear. regards, Carl -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com

Hi All, Thank you all very much for your comments, I mistakenly posted 128 Mb ram instead of 256 (more sleep needed;)), but sure it has to be added. I will add it as soon as my wallet gets off the "drunk" state.
Here what I have done for optimizing performance. First off all I switched off all unused services(posted in previous letter) from chkconfig. Switched off mingettys which I do not need. For OpenOffice I have done the following(please correct me if I have done bad thing) From the Tools -> Options in the Memory tab, I increased the value for Graphics Cache use for OpenOffice.org to 128 Mb, and increased Memory per object to 20.0 Mb. The Office performance increased maybe not significantly, but quite a good, and at least the selecting of a text became much more easy thing to do :) doing linux:~ # hdparm -t /dev/hda6 gives /dev/hda6: Timing buffered disk reads: 60 MB in 3.05 seconds = 19.68 MB/sec I tried to do something like linux:~ # hdparm -m2c3u1 /dev/hda6 which gave /dev/hda6: setting 32-bit IO_support flag to 3 HDIO_SET_32BIT failed: Invalid argument setting multcount to 2 HDIO_SET_MULTCOUNT failed: Invalid argument setting unmaskirq to 1 (on) HDIO_SET_UNMASKINTR failed: Invalid argument multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) and doing linux:~ # hdparm -d1 /dev/hda6 gives... /dev/hda6: setting using_dma to 1 (on) HDIO_SET_DMA failed: Invalid argument using_dma = 1 (on) Do I did correct thing in OpenOffice, and should I do something with hdparm's?
