Machine #1: Pentium 90mhz, 64M ram, running Linux 2.4.something kernel + X windows. Video is an old Cirrus something or other 1M onboard vram.
Machine #2: 386DX-25(with 387) 16M ram, running OS/2 Warp 3. Video is IBM 8514, 1M onboard vram
Both have a pair of 9G ST410800N fast SCSI-2 drives.
Machine #2 is dramatically more responsive and snappier than machine #1.
Yea, the OS/2 kernel and 8514 drivers have a lot of hand tuned assembler code, but still. The difference is dramatic. The OS/2 386 is actually usable to sit at and work on while the Linux box is really torture.
I want to like Linux, I really do. But its a pig, it really is.
