Re: [ossig] Hard disk optimization, and maybe notebook optimization2
Normally 1 of four things slows down a PC :
too slow CPU (shouldn't make any sudden changes), insufficient
memory, hdd in the wrong mode, accidental running of
heavy background jobs.
hdd wrong mode:
Did you get the hdparm working? My guess, if you did not, is
that the hdd may be working in PIO mode not UDMA mode. hdparm
should probably be able to fix that.
heavy background jobs:
top (as suggested) or uptime is your next best bet. leave
the thing alone for 5 minutes, then run 'uptime'. if it's
not close to 0, there is something running in the background
all the time, slowing other stuff down.
insufficient memory:
You just switched to RH9, right? Maybe that has a higher
memory requirement that has pushed you over the limit?
What's your memory usage?
once you get 'top' figured out, try 'ksysguard'. it's all
the system monitoring graphs you could ever need. the memory
distribution graphs are very helpful to see if you need more
memory - in an ideal system, you should have large amounts of
'buffer' and 'cache' after running for a few minutes, ideally
>50% of your total memory. my personal benchmark is to
buy 2-4 times more memory than most new PCs have :), so that 75% of
it is cache space and my hard disk is barely accessed when running
all the common programs (oo.o, mozilla etc).
however, you mention terminal is slow. is that to a remote
machine, or local? if remote, maybe your network has problems?

Thanks for the info. I find that my notebook suddenly seems "slow". takes awhile to boot up, takes a very long while to start sendmail, snmptrapd.
Once in the GUI, starting a TERMINAL session is a patience game. What has happened? It was not like this over the weekend. FYI, I run a dual boot configuration - WimME & RH9. I am trying to set up SNORT-MYSQL-ACID.have not installed anythign yet. Only thing i did was to try to install the embedded linux workshop and installed busybox.
Everything seem sloooooww. Any particular places that I should look at?
