I'm hoping that once yarrow is threaded performance will return to a usable level. Keep in mind that a 486 is relatively powerful compared to the available systems when X was designed. >I do not really think the latest XFree86 versions were designed >with running 386/486 in mind. 386/486 is still a market, but >not many people try to build an embedded system with a full X >and tools. I'm running XFree86 3.x, rather than 4.x. I agree that X is unlikely in most embedded applications, but blocking in the kernel for an extended period is likely to be equally unacceptable.
