Basicly I did a make xconfig in the kernel tree I had already built and 
was running, with an eye to getting rid of that which isn't of any 
perceived usefullness to me.  If, as you go thru the xconfig screens item 
by item, you read the help that pops into the lower right corner of the 
window, and it says "if you don't know what this option does, you 
probably don't need it, say N".  By the time I got down to the bottom 
of 'block devices' I'll bet I'd turned off a hundred things that were 
being built, and which had no earthly use to me, but the previous 'make 
oldconfig' had enabled them.  With this newer compiler seemingly being as 
slow as it it, that cut the build time by about 7 minutes, down to 24 
IIRC, but I can recall building a kernel for this machine in under 8 
minutes back in the mists of time.  And the system, once booted to it, 
does seem a bit snappier at some operations.  I think I can probably cut 
that much more the next time I have half an hour to work in an xconfig 
window.

Firefox launch times?  Not a huge speedup there so far.  Sorry.
