Do these comments apply to ULE with and without the patch? Is there any difference? I suspect that your interactivity problems in this situation are more due to disk and memory pressure. If you were to fire up vi, or a shell, something that's totally memory resident, do they suffer any lag? Also, how well does 4BSD do in this same test? Thanks!
