Here is a chart of compile times for several machines in our lab
for approximately 1820 lines of C source with comments:
Sun3/60 Sun4/260 Apollo DN4500 Mac IIx(8 megs)
45 s 27s 38s 3min 11s
Everex 386 Step20(4 megs) (8 megs) Sun386i
2min 5s 1min50s 57s
I wouldn't think of comparing the Mac to the higher priced workstations,
but the Everex's running ISC's Unix are significantly faster than the
Mac. Are we doing something wrong? Has anyone else noticed this?

Are we doing something wrong? Has anyone else noticed this? Well, yes (doing something wrong). You are comparing apples and oranges. Unless you are running the exact same C compilers on each machine, then you have a large part of the benchmark measuring compiler speed, not machine speed. For example, on a Mac II, I'm compiling over 2000 lines of C in 22 seconds -- but using LSC under Mac OS. However, it only takes 1m23s under A/UX. I don't know why you are taking 3mins+ +------------------------+-----------------------+----------------------------+ | Philip K.

Actually when comparing compilers in this manner you should first run the source through cpp, because some systems may include many more .h files than you expect (from includes within includes within .....).
