A while back, someone posted a "Whetstone" benchmark to comp.sys.dec in both
FORTRAN and C (from AURORA::HALLYB). I compiled said benchmark for two machines:

1) MicroVax3100 / VMS5.3 / VAXC 2.2
2) Dell Sys310 (386/20) w/80387 FPU / Dell UNIX SVR3.2 (ISC 2.0.?) / "Stock" C

The puzzling thing is that performance on the 386 was 20% SLOWER than the
MV3100. From what I have been told, the 3100 is a relatively low-end machine
and a 386 should outperform it (the Dell is a pretty fast machine). The general
"response" of the MV3100 seems to go along with this.

Is there something unusual about VAXC or the architecture of the machine that
could cause this ?
