Hi list, Once again my FC4 box (Duron 1200mHz, 512 ram) has crawled to a halt. I quickly top'ed and found a process prelink that varied between 74%-98% CPU usage. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5202 root 39 19 11724 9280 536 R 89.9 1.9 0:23.59 prelink So I googled for prelink and now know that it helps preload libraries so that progreams can start faster. Which is senseable because the machine started slowing down when I clicked 'manage bookmarks' in firefox, which opens another program. My question is, what can I do to prevent this from happening again? Do I have to ust cross my fingers every time I open a new program? Could this be related to the fact that I have no swap partition? I know that I should probably add one, I guess that I've just been too lazy to learn how. Will adding a swap partition make the machine less sluggish? For this 512 ram machine, I was thinking of adding a 2 gig swap partition. Dotan http://lyricslist.com/lyrics/artist_albums/60/basil_toni.php Basil, Toni Song Lyrics
