proc nlin performance

hi,

i'm running a proc nlin on a large data set, it takes forever to complete.

it runs on a big unix server with 32gb memory.

on the unix performance monitor i see that it is using full i/o and almost no memory, only 27mb.

i would expect proc nlin to be memory intensive and use a lot of it when available. is this assumption correct?

are there suggestions for performance tuning?

proc options group=memory; run;

returns:

SORTSIZE=4294967296

Size parameter for sort

SUMSIZE=0 Upper limit for data-dependent memory usage during summarization

MAXMEMQUERY=6291456

Maximum amount of memory returned when inquiring as to available space

LOADMEMSIZE=0 Suggested memory limit for loaded SAS executables

MEMSIZE=8589934592

Specifies the limit on the total amount of memory to be used by the SAS System

REALMEMSIZE=17179869184

Limit on the total amount of real memory to be used by the SAS System

never mind this, input data for proc nlin was a view that was taking a long time to resolve.
