There is very little physical paging activity. What is happening a lot is the application is using memory for the first time and/or doing malloc.
Also, when physical i/o activity is taking place, you are writing 14x for each read
Your high number is just showing what I hope is normal startup activity. You have lots of memory free - so file caching is easy (also explains why writes dominate read activity)

pfm_enable_faults
pfm_enable_faults(3ncs)pfm_enable_faults(3ncs)Name
pfm_enable_faults - enable asynchronous faults
Syntax
#include <idl/c/base.h>
#include <idl/c/pfm.h>
void pfm_$enable_faults()
Description
The routine enables asynchronous faults after they have been inhibited by a call to causes the operating system to pass asynchronous faults
on to the calling process.
While faults are inhibited, the operating system holds at most one asynchronous fault. Consequently, when returns, there can be at most
one fault waiting on the process. If more than one fault was received between routines to and the process receives the first asynchronous
fault received while faults were inhibited.
Diagnostics
This section lists the status codes for errors returned by this routine.
pfm_$bad_rls_order Attempted to release a clean-up handler out of order.
pfm_$cleanup_not_found
There is no pending clean-up handler.
pfm_$cleanup_set A clean-up handler was established successfully.
pfm_$cleanup_set_signalled
Attempted to use pfm_$cleanup_set as a signal.
pfm_$invalid_cleanup_rec
Passed an invalid clean-up record to a routine.
pfm_$no_space Cannot allocate storage for a clean-up handler.
