Acroread presented beautifull interface and appearance, evince is moderate in appearance and xpdf ...... too simple appearance.
My machine is Lenovo T61, T7500 Intel Santa Rose processor and 4 GB Physical RAM :=))
Opening ACROREAD 8 required * (eight) SECONDS from clicking document up to visible display
Evince spending 3 (three) SECONDS from clicking document up to visible display
XPDF need 1 (one) SECOND from clicking documents up to visible display.
ACROREAD is very beautifull appearance, but very slow .... comparing to the ugly XPDF. But for speed ... Nothing Compare to XPDF.
Choice are there ..... your finger decided
