On the other hand, kicking most of the operating system off the machine,
as you do when running as a diskless boot, saves considerable memory.
That memory can serve an excellent purpose of running as a ramdisk;
especially if you use the 2.4 kernel capabilities for VFS for this.

Now, if you have a background thread that loads and unloads your
local memory cache ahead of the game needing the data, then you may
get noticably better performance.  After all, your kernel is running
with most of the hardware drivers disabled (so interrupt load is low).
