OK this is my take, I know that I cannot give you all quantitative 
measurement, but let me share my perception :

I have two identical DIY desktops, Duron 800 MHz, 1GB SDRAM PC133. One 
with Fedora always from FC2 4.7, just reinstalled from FC4 to FC5, the 
other one for my wife is using Ubuntu 5.10 because its sudo style 
instead of having to know the root pasword.

I am used to view DivX movies on the desktop using xine+xvidcore/divx4linux.

When I was in FC4, I have no problem viewing DivX movie, I can jump to 
any scene just using the slider. But now after I upgraded to FC5, 
everytime I slide, the movie pause for about 3-4 second before continue 
the play. Even if I want to stop or pause the movie, xine will response 
for 3-4 seconds later.

For the Ubuntu 5.10 it does not have a problem, same as FC4

Another comparison is for Firefox browsing, it feels slow also in FC5. I 
notice that if I make the click above a hyperlink and dragging the 
mouse, sometimes the pointer becomes the "copy+paste" (with a symbol of 
paper into it) instead of the waiting (circling logo) and I ends up 
pasting something to another tab windows. I have a feeling that the 
system might interpret my click too late, and taking the pointer 
position not the same as what being displayed on the screen. I mean, I 
click the position (x1,y1), but since it respons later while my pointer 
is moving, to another position (x2,y2), it respons to (x2,y2) click. I 
still cannot explain the phenomenom very well. Does anybody ever do 
browsing using Solaris 8 SPARC with Netscape Navigator 4.71? It has the 
same sense of sluggishness.

Just my 2 cents rambling,
