Did you stripped the djgpp file? or this file have all the debug information 
inside?

Hmm... I think these values are wrong. What switchs did you used for djgpp?

DJGPP programs aren't greater than Watcom, the first reason is that any 
Watcom program needs the extender and normally it means 240Kb. Additionally 
you can compress the djgpp exe files.
In speed I saw small differeneces, some times in favor of djgpp, normally 
Watcom programs are marginally faster and some times they are faster, but 
never numbers like you say.
DJGPP is popular because:

1) The cost is 0 vs ??? U$S.
2) The support for djgpp is the newsgroup and works very well. I never saw 
such a support from a PC software company (I used Borland products).
3) You get all the sources of the libraries, that's very important for most 
of the serious applications. If you don't have the sources you must live with 
the bugs in the libraries and that's impossible to tolerate.
4) I don't know about the Watcom's IDE but some people asked about using 
RHIDE (one of the djgpp IDEs) for Watcom so I think Watcom's DOS IDE is very 
bad.
5) DJGPP is much better for ports from and to UNIX and that's important.
etc, etc.

That's why is popular.
