RAM (and Speed)

[René L. Reingard]

Dear Vince,

you are fast in reply - you guy must sit in front of the computer half  
your life! right?
correction: this machine has 256 RAM. but, anyhow.

the loading in the beginng (before entering name ans password) takes time  
(at least compared to XP on the same machine). i guess about one minute  
(?). after name and password, Gnome starts within 20 to 25 seconds (?). i  
haven't checked the real time so far.
also when opening Nautilus it can take more time than desired. there is no  
such a thing like fast response on clicking my home folder. i guess it can  
take up to 5 seconds.

$ hdparm -t dev/hda tells me about a reading speed of 22.0 MB/sec.

what could be optimal parameters?
i once have seen a site where some guy was talking about tweaking the HD.   
but isn't it highly risky?

René
