According to my man page, it would appear you have a choice of three
malloc's with different performance options, with the default being one that
ballances speed and efficency. From my Solaris 8 (Sparc) malloc man page:
USAGE
Comparative features of malloc(3C), bsdmalloc(3MALLOC), and
malloc(3MALLOC) are as follows:
o The bsdmalloc(3MALLOC) routines afford better perfor-
mance, but are space-inefficient.
o The malloc(3MALLOC) routines are space-efficient, but
have slower performance.
o The standard, fully SCD-compliant malloc routines are
a trade-off between performance and space-efficiency.
So it would seem if you had a lot of ram, you could try a
#define malloc bsdmalloc
and see if that improved things.
