UniVBE supports more video cards than svgalib, so you may be getting a
linear frame buffer under DOS and not under svgalib.  If you have a
linear frame buffer on both, they should be about the same speed
(although actually the svgalib port uses hardware accelerated rect
fills, something the DOS port won't be able to do until UniVBE 5.2
comes out).

One way you can tell if you have a linear frame buffer under svgalib
is to start executor in 8bpp mode and bring up the alt-shift-5 panel.
If your only choice is 8bpp, then you've got a linear frame buffer.
This is caused by an svgalib limitation; if you've got a linear frame
buffer, you can get other modes and take a performance hit if you
start Executor in something other than 8bpp.
