On my alphas, I get:

Machine		   egcs-1.1.1		  egcs-1.1.2
-------		   ----------		  ----------
Multia:		 91407.7 Dhry/s		 91743.1 Dhry/s
PWS433a:	440528.6 Dhry/s		497512.4 Dhry/s
AS200 4/233:	173010.4 Dhry/s		170648.5 Dhry/s

where the PWS433a has no off chip cache.

I tried BWX but it didn't seem to make any difference.

I'm not sure why my multia and yours achieved such different values, but
the interesting config of mine is:  NetBSD 1.4.1, 64MB Ram.
