All aspects of the >entropy harvesting have changed significantly since PRE_SMPNG. I upgraded to -current as of last Friday (this took most of the weekend on my 486DX2-50, so I didn't do much experimenting). The entropy seeding during startup takes a couple of seconds - not a problem. X seems somewhat better, though the performance is still not acceptable - the mouse movement will freeze for a second or so occasionally. (I just pull up a longish menu from fvwm and scan the mouse up and down). Overall, entropy harvesting in -current has improved significantly since PRE_SMPNG, but IMHO there is still some way to go before its acceptable on slower machines.
