Trinity on older hardware

All, Do you have experience with running Trinity on older hardware? I have a PI and a PII. For years I ran KDE 3.5.10 on both. While hardly the fastest hardware, and 3.5.10 hardly the snappiest desktop environment, the system was usable. Trinity R14 on both systems is almost unusable. Starting Trinity takes a minute or two. Opening konsole takes 7-10 seconds. Opening a preloaded konqueror takes 20-25 seconds. I realize free/libre software never truly supported older hardware despite claims otherwise and developers instead move relentlessly onward with bleeding edge hardware. Still, because of the many improvements I would think Trinity R14 would fare better, at least as good as 3.5.10. Any ideas? Any help? Darrell
