The C++ compiler is a memory hog.  On your memory-starved machine it 
pages like hell, and is therefore much slower.

If at all possible, add memory.  If not, use every trick in the book to 
make your DOS file I/O as fast and as efficient as you can.  You didn't 
post any system configuration info, so I'm unable to give specific 
advice, but section 3.9 of the DJGPP FAQ list has some guidelines, 
including for memory-starved machines.

There is an opinion at large that vendors and programming language 
designers have conspired to push us to buy ever faster and 
memory-abundant machines...

Another alternative is to not use C++ ;-).
