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. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
