This performance issue looks to be a RAM and/or Video Card problem to me.
Things to check: Make sure you aren't using DoubleSpace/DriveSpace or similar. Close any apps in the system tray that aren't needed. Close your virus scanner, or put it to sleep at least. If it is scanning every file that loads that is not going to help. Especially as the current breed will uncompress zip, gz, tar and Z files when it sees them. Try running the System Monitor applet watching CPU, free RAM and Swap file usage, then fire up FGFS. I predict that the swap file usage will go through the roof. You may need to turn the update rate down to get the graph to cover all of startup. It might be worth trying a non-debug build, as this will almost certainly have a smaller memory footprint. Alternatively, get the 256MB upgrade out of the wings, and into the DIMM sockets. If that doesn't help, get a GeForce2MX or better for your video card. When I went from a Diamond 3D 2000 to a GeForce 2MX, my frame rate on Win98SE went from <1fps to 30+. The top speed of Magic can be tweaked in src/Main/fdm/magic.cxx (I think that is the right place). I usually remap it to be proportional to throttle^2, and have a max value nearer 10000 knots. Remapping to throttle^2 means that you maintain a little bit of control at low speeds. FWIW, I get adequate performance (~10fps) on P200MMX, 64MB Ram, with a cygwin debug build. But the disk does thrash some.
